In the current global economic and technological environment, integrating geological CO2 storage with enhanced oil recovery is the most practical way to reduce green-house gas emissions and increase the energy supply (CCUS). The overlapping development of large-scale coal conversion industries with existing oil and gas industries in the Ordos Basin, Northern Shaanxi Province has created a unique opportunity to apply a systematic approach to an energy/environmental protection development strategy: The integration of geological CO2 storage and enhanced oil recovery utilizing CO2 flooding (CO2 EOR) and geological storage that has been developed in Wyoming. The coal conversion industry in the Ordos Basin (i.e., coal-to-methanol, coal-to-olefins, etc.) provides affordable, captureready CO2 sources for developing large-scale CO2 EOR and CO2 storage projects in the Ordos Basin, China. Currently, over 40 Mt of highly concentrated CO2 (> 95%) are being captured and vented from the methanol plants. Compared with other CCS projects, the ability to use CO2 from the coal-conversion industry for CO2 EOR and geological CO2 storage will make these CCUS projects in the Ordos Basin more cost effective, technologically efficient, and environmentally sound. Supported by US-China Clean Energy Research Center, Shaanxi Provincial Government, and Yanchang Petroleum Group Company, the University of Wyoming, Shaanxi Provincial Institute of Energy Resources and Chemical Engineering, and Research Institute of Yanchang Petroleum (Group) Company have developed a CO2 enhanced oil recovery demonstration project that includes geological CO2 storage in a mature, depleted oil field located in the Northern Shaanxi Province, Ordos Basin. Various scenarios for enhanced oil recovery using CO2 flooding integrated with geological CO2 storage are being simulated and optimized. The results of the reservoir characterization and CO2 flooding simulation show that integrating CO2 EOR with geological COv storage is a viable way to reduce CO2 emission in the region. © 2014 The Authors.

Letter of Intent paves the way for CBM success in China's energy prolific province LARAMIE, Wyoming, Nov. 12, 2016 /PRNewswire/ -- WellDog announced today that is has signed a Letter of Intent to form a joint venture with the Shaanxi Provincial Institute of Energy Resources and Chemical Engineering (SPIERCE). The joint venture will deploy reservoir, production and development technologies to demonstrate profitable coal bed methane (CBM) development in fields located within the Shaanxi province, one of China's most prolific energy resource regions. "The introduction of WellDog technologies will contribute greatly to the efficient development of CBM and other unconventional oil and gas resources in China," stated SPIERCE Director Dr. Zhou Lifa. China's CBM resource is estimated at nearly 40 trillion cubic meters (tcm), with recoverable reserves of about 10 tcm. Over the last few decades, China has dramatically increased investment in CBM technologies, and each of the country's five-year plans has increased CBM production targets, but the results to date have failed to meet those goals. "We believe we have the operational and technical know-how to make a dramatic improvement in Chinese CBM production," said John Pope, Ph.D., president and CEO of WellDog. "We started in 1999 at the very infancy of CBM and have become one of the major global players in delivering successful CBM technical services to basins around the world. Bringing WellDog's know-how and technologies to China will enable the Chinese producers to maximize value from their assets and hopefully meet their production targets in the near future." The joint venture meets WellDog's strategic goal of driving georesource innovation to improve sustainability. "Shaanxi has committed to producing 20 billion cubic meters of natural gas by the end of the 13th five-year plan," said James Walker, WellDog Chief Operating Officer. "The dramatic increase is part of China's push to ease off of burning coal and switch to natural gas, which would substantially improve the average quality of life of Chinese residents." ABOUT WellDog: WellDog is an energy-focused technical services company that provides practical technical and business solutions in a high volume, cost effective manner with a remarkable customer focus. The company's mission is to develop and deploy innovative technologies to produce resources faster, responsibly and sustainably.

A series of catalysts used for synthetic ammonia from methane and nitrogen at atmospheric pressure were prepared by the fractional wetness impregnation method. Based on the performance comparisons of iron catalysts among different supports, the coconut shell activated carbon displayed an excellent catalytic activity than SiO2, γ-Al2O3, and columnar carbon. Through the promoter selection experiments such as Zr, Ce and K, we found that the K promoted iron catalyst has the highest synthetic ammonia rate. XRD, SEM, and BET were carried out to characterize the supports and catalysts, and the results showed coconut shell activated carbon has the most uniform pore distribution with outstanding increase of average pore volume. A crystalline phase of KFeO2 was generated after the catalyst reduction. The optimal loading sequence and working conditions of synthetic ammonia catalysts were investigated in a fixed bed differential reactor. Experimental results prove that atmospheric pressure, 700 ℃, VCH4/VN2=2/1, flow rate of 2 800 mL/h, 3%K-5%Fe/cocoanut-char can achieve the most favorable synthetic ammonia rate of 1.04×10-6 mol·g-1·s-1, which is 83.5 times higher than current literature and would foresee an extensive prospects of industrial application in the future. © 2015, Science Press.

Aimed at exploration of basin-mountain coupling relationship between North Qinling Mountains and Liuyehe basin, the authors employed the detrital zircons age dating of the Carboniferous-Permian sedimentary rocks from Liuyehe basin located in North Qinling Mountains. The U-Pb dating results of 82 zircons gave rise to six age groups in an age range of 264±5~2834±40 Ma, 260~542 Ma, 800~1100 Ma, 1320~1560 Ma, 1640~2250 Ma, 2300~2660 Ma and 2720~2870 Ma. Among the groups, the 260~542 Ma age group represents the largest proportion of the measured points, followed in succession by 1640~2250 Ma group, 2300~2660 Ma group and 800~1100 Ma group. A comparative study of the age structure and the Carboniferous cross-bedding shows that the provenance of the Liuyehe basin during the Carboniferous-Permian was probably located in the North Qinling Mountains during the Late Paleozoic. In addition, the detrital zircon age structure comparison shows that the sedimentary rocks of the southern Ordos basin and the Liuyehe basin have the same age spectrum characteristics, which in turn means that they had the same provenance during the Permian. Under the influence of late Caledonian orogeny, North Qinling area experienced rapid uplift and eventually completed the evolution of basin-mountain conversion. Later, along with the Shangdan strike-slip fault, the Liuyehe basin began to form due to the opening-up of the Mianlue Ocean, while the North Qinling Mountains became its main provenance. ©, 2015, Science Press.

Abstract: Ni incorporated catalysts with different ratios of Ce/Zr were prepared via a one-pot surfactant assisted Pechini method, and dry reforming of methane was used to evaluate their performances. The prepared catalysts were characterized by nitrogen adsorption–desorption, XRD, SEM, TEM and TGA. The nitrogen physisorption analysis witnessed the distinctive mesoporosity of NiCe0.5Zr0.5O3. The TEM observation confirmed a homogeneous dispersion of NiO nanoparticles within the mesopores, and the XRD presented a high crystallinity of NiCe0.5Zr0.5O3 within relatively smaller particle size. After 6 h dry reforming of methane in a fixed-bed reactor, the minimal carbon deposition was detected on the used NiCe0.5Zr0.5O3 among the NiCexZr1-xO3 (x = 0.1, 0.5, 0.9) catalysts, and XRD result also indicates nano-sized NiO particle on the fresh catalyst will be of great benefit to the resistance of carbon formation. The mesoporous structure of NiCe0.5Zr0.5O3 was achieved at Ce/Zr = 1:1 and NiO particles incorporated in the pore were also clearly observed based on the characterization results. The catalytic evaluation experiments prove its remarkable initial activity (CH4 94.0 & CO2 97.2 %), minimal carbon formation, and outstanding catalytic performance at different WHSVs. Graphical Abstract: A series of NiCexZr1-xO3 catalysts were prepared and the optimal synthesis ratio of Ce/Zr is 1:1 based on the characterization results. NiCe0.5Zr0.5O3 presents a few features such as mesoporous structure, highly dispersed NiO, large surface area, and small crystallized sizes. DRM reaction experiments also prove NiCe0.5Zr0.5O3 has remarkable catalytic performance.[Figure not available: see fulltext.] © 2016 Springer Science+Business Media New York

CexZr1-xO2 supports were prepared by coprecipitation methed. 10% Ni-3% La catalysts supported on CexZr1-xO2 were produced by an fractional wetness impregnation method and applied in syngas production, using coupled methane partial oxidation and CH4/CO2 reforming. The series of 10% Ni-3% La/CexZr1-xO2 (x=0, 0.16, 0.5, 0.75, 1) catalysts were characterized by X-ray diffraction, H2 temperature-programmed reduction, scanning electron microscope etc. Experimental results show that Ce/Zr solid solution can improve the dispersion of active components on catalyst surface, reduce the NiO crystalline size from 26.5 nm to 13.5 nm. Moreover, it can strengthen the interaction between active metal and supports, boost the thermal stability of the catalysts. The conversion, selectivity and stability of the catalysts were enhanced with the increase of Ce/Zr ratio as follows, Ni La/Ce0.75Zr0.25O2>Ni La/Ce0.5Zr0.5O2>Ni La/Ce0.16Zr0.84O2.

The Shaanxi Province/Wyoming CCS Partnership (supported by DOE NETL) aims to store commercial quantities of CO2 safely and permanently in the Ordovician Majiagou Formation in the northern Ordos Basin, Shaanxi Province, China. This objective is imperative because at present, six coal-to-liquid facilities in Shaanxi Province are capturing and venting significant quantities of CO2. The Wyoming State Geological Survey and the Shaanxi Provincial Institute of Energy Resource and Chemical Engineering conducted a feasibility study to determine the potential for geological CO2 sequestration in the northern Ordos Basin near Yulin. The Shaanbei Slope of the Ordos Basin is a huge monoclinal structure with a high-priority sequestration reservoir (Majiagou Formation) that lies beneath a 2,000+ meter-thick sequence of Mesozoic rocks containing a multitude of lowpermeability lithologies. The targeted Ordovician Majiagou Formation in the location of interest is more than 700 meters thick. The carbonate reservoir is located at depths where pressures and temperatures are well above the supercritical point of CO2. The targeted reservoir contains high-salinity brines (20,000-50,000 ppm) that have little or no economic value. The targeted reservoir is continuous as inferred from well logs, and cores show that porosity ranges from 1 to 15% with average measured porosity of 8%, and that permeability ranges from 1-35 md. This paper focuses on calculations that will help evaluate the capacity estimates through the use of high-resolution multiphase numerical simulation models, as well as a more simple volumetric approach. The preliminary simulation results show that the Ordovician Majiagou Formation in the Ordos Basin has excellent potential for geological CO2 sequestration and could store the CO2 currently emitted by coal-to-liquid facilities in Shaanxi Province for hundreds of years (i.e., 9 Mt/year CO2; 450 Mt over a 50-year period at one injection site). © 2011 Published by Elsevier Ltd.

Graphene (GN) and silicone-acrylate emulsion composites were prepared by joining graphene solution which was obtained by chemical reduction-oxidation and ultrasonic dispersion into acrylic emulsion. The graphene was characterized by XRD, AFM and IR and the composite films were characterized by SEM, TG, electrical conductivity, anti-corrosion performance test, mechanics performance and water resistance test. The results show that the graphene obtained from graphene oxide by reduction reaction is better and was successfully dispersed with nanoscale thickness. The composites exhibit excellent electrical properties with a percolation threshold as low as 0.5% and a stable volume resistance below 103 ω·cm when the graphene content is more than 0.9%. In addition, when the additive amount of GN reached 0.7%, compared with silicone acrylate emulsion, the tensile strength of the composite materials increases by 15.5%, the elongation at break decreases by 3.6% and the decomposition temperature increases nearly 43℃, the performance of resistance to water increases by 14% and corrosion resistance is greatly improved.

A cooperative project between Shaanxi Provincial Institute of Energy Resources and Chemical Engineering and the Carbon Management Institute of University of Wyoming is being carried on in the Ordos Basin, aiming to integrate CO2 storage with CO2 -EOR. This paper reports on the characterization of the targeted reservoir where CO2 is to be injected. Characterization of the reservoir provides the basis for a geologic model to support the CO2 injection simulation, and to develop injection strategies. Petrophysical well-logs were integrated with detailed core descriptions, thin sections and core analysis data into provide insight to the reservoir characteristics, pore structure features, and depositional environments. The upper Triassic Yanchang Formation, composed of clastic rocks is the main reservoir in the study and is located at field A in the Shaanbei slope of the Ordos basin. Although the field has been developed since 2003, water flooding development at present is constrained by low permeability, low porosity, high heterogeneity, high capillary pressure and high content of cementing material. The sandstone of the Yanchang Formation is essentially a delta front subfacies depositional system and has two main microfacies. One is sub-aqueous distributary channel, with an average porosity of 10.31% and permeability of 0.35x10-3μm2; the other is interdistributary bay. Integration of petrophysical well-logs, detailed core descriptions, thin sections and core analysis data provide insight into the facies interpretation, and provide the basis for the later reservoir modelling and injection simulation. The next step will be to build a 3D geologic model and then choose the most suitable sand body to perform on injection simulation. Although many CO2 -EOR projects have been proven effective and bring satisfactory financial. © 2014 The Authors. Published by Elsevier Ltd.
