Acidic ionic liquids (AILs) as a novel catalyst in biomass liquefaction can accord with the demand of green chemistry and enhance the development of biomass thermal chemical conversion. A series of AILs containing HSO4- were synthesized by the imidazolium cation functionalization and applied to the Chinese fir sawdust liquefaction in 1-octanol in this paper. The experimental results showed that the liquefaction rate was gradually improved with the AILs acidity increasing, and reached 71.5% when 1-(4-sulfobutyl)-3-methylmidazolium hydrosulfate was used as catalyst with the 6:1 mass ratio of 1-octanol to sawdust at 423. K after 60. min. Lignin, hemicellulose and cellulose were orderly desquamated, and then depolymerized and liquefied with the catalyst acidity increasing in the sawdust liquefaction process. The light oil was mainly composed of the octyl ether and the octyl ester compounds, suggesting that the solvent may play an important role in producing the high octane rating biofuel. © 2013 Elsevier Ltd.

In this study, a rapid and simple calculation procedure to determine the non-isothermal crystallization kinetic parameters of a glass was proposed based on the work of Matusita et al. The crystal growth index (n) was firstly determined with the equation proposed by Matusita in 1979 and the value of morphology index (m) could be determined according to the relationship between n and m. The activation energy for crystal growth was determined using the modified-Kissinger equation proposed by Matusita in 1980. To verify the validity of this efficient and rapid method, four compositions in the Li2O-SiO2-Al2O3-P2O5 glass system were investigated by scanning electron microscopy (SEM) and X-ray diffractometry (XRD). The crystallization mechanisms as identified by the characterization show good agreement with those predicted by the new calculation procedure, verifying the validity of the calculation procedure. © 2016 Elsevier B.V.

This article discusses MPCA (Multi-way Principal Component Analysis) and MPLS (Multi-way Partial Least Squares) have been used to compress the information into low-dimensional spaces and pinpoint the root causes of batch-to-batch difference. From engineering perspective, this paper focuses on applying MPCA and MPLS to data analysis of batch process combining with operation experiences to find 'golden batch benchmark' that describes the best operation of historical batches. This work includes data pre-treatment, batch process modelling and chemical reaction initiation status decision. Finally, optimizing control strategies and batch process improvement are also been discussed. Process and control engineers are be able to obtain the valuable data analyzing and control optimization methods for batch process from this study. © 2016 IEEE.

A spray drying approach has been used to prepare polyurethane/multiwalled carbon nanotube (PU/MWCNT) composites. By using this method, the MWCNTs can be dispersed homogeneously in the PU matrix in an attempt to improve the mechanical properties of the nanocomposites. The morphology of the resulting PU/MWCNT composites was investigated by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). SEM and TEM observations illustrate that the MWCNTs are dispersed finely and uniformly in the PU matrix. X-ray diffraction results indicate that the microphase separation structure of the PU is slightly affected by the presence of the MWCNTs. The mechanical properties such as tensile strength, tensile modulus, elongation at break, and hardness of the nanocomposites were studied. The electrical and the thermal conductivity of the nanocomposites were also evaluated. The results show that both the electrical and the thermal conductivity increase with the increase of MWCNT loading. In addition, the percolation threshold value of the PU composites is significantly reduced to about 5 wt % because of the high aspect ratio of carbon nanotubes and exclusive effect of latex particles of PU emulsion in dispersion. © 2012 Wiley Periodicals, Inc.

Taking a 50 thousand t/a electronic grade epoxy resin plant in Blue Star New Chemical Material Co., Ltd., as example, the greater influence factors on energy consumption of epoxy resin plant are analyzed. The results show that the energy consumptions for 1.05 MPa steam, nitrogen and circulating water are 64.83%, 18.66% and 12.06% of total energy consumptions, respectively. Special measures are taken to reduce the unit consumption for three energies in different phases, which make the overall energy consumption decrease from 358.52 Kgce/t epoxy resin to 292.73 Kgce/t epoxy resin.

A novel nano-sized Co-Ni bimetallic aerogel catalyst was synthesized via the sol-gel process followed by the supercritical drying method. The catalyst exhibited at least 28% higher activity and 15% higher H2 selectivity than those of a monometallic cobalt aerogel catalyst in methane oxidative CO2 (Oxy-CO2) reforming. Cold-model experiments revealed that channels were alleviated and the agglomerate size was reduced when the catalyst was applied in a magnetic assisted fluidized bed (MAFB). Owing to the improved fluidization quality of the catalyst in the MAFB reactor, CH 4 conversion was raised by 12% and 7% as compared with those in the fixed bed reactor and the conventional fluidized bed reactor, respectively. Furthermore, the catalytic performance was quite stable during a 50 h reaction. This stable performance can be illustrated both by the superior catalytic property of the Co-Ni bimetallic aerogel catalyst and the intensified gas-solid interaction in the MAFB reactor. © 2010 Professor T.

This paper focuses on the influence on traffic flow characteristics of distance between on-ramp and off-ramp in expressway. In this research, those characteristics include traffic flow rate, average speed and average density. Based on VISSEVI, we calibrated key parameters and a calibrating procedure is proposed. Then we simulated scenarios with different distances from 100m to 1000m. Analyses of the distance's influence on traffic flow characteristics are studied using simulation results. A step further, 3 modes are classified out of different distances and 2 thresholds are proposed. The two thresholds are within 100-200m and 500-600m and if distance varies through these, traffic flow characteristics will change significantly. Finally, as for verification, we compared 3 scenarios of simulation with reality. In the future, different control strategies may be applied due to different conditions. © 2012 IEEE.
