NiMo/ZSM-11/mordenite catalyst was developed for isodewaxing process of middle distillate fractions of oil and Fischer-Tropsch synthesis products to obtain diesel fuels for Arctic service and jet fuel. The catalyst contains the promoters B2O3, La2O3 and the mixture of amorphous aluminosilicate and γ-Al2O3 as a binder. During testing of the catalyst at pressure 3 МPа, volume ratio hydrogen/feed 600 m3/m3, temperature 310 °С, LHSV 2.0 h− 1 jet fuel with chilling point not higher than 60 °С below zero and diesel fuel with cold filter plugin point not higher than 44 °С below zero were obtained with the yield 91.7% wt. © 2017 Elsevier B.V.

In world practice bioethanol is widely used as a component for standard motor gasolines, with concentration 5–15% by volume (E5, E10, E15 fuels) or as bioethanol fuels with ethanol content from 20% till 85% by volume (E20-E85 fuels). Currently in Russia the motor biofuel and its components are not used. At the same time, the development of biotechnologies and bioenergy is the priority task of the scientific and technical policy of the State. The complex program sets the goal to increase the consumption volume of motor biofuel up to 10% till 2020. It should be achieved primarily by bioethanol production, which will be used as a component of automotive gasolines or for production of bioethanol fuels. Bioethanol in Russia can be used in essentially different ways: 1) as a high-octane component in concentration not higher than by 5% by volume for the production of motor gasoline 2) as a high-octane component in concentration not higher than 10% by volume for benzanol (gasohol) production 3) for ethyl tertiary butyl ether (ETBE) production 4) as a component of bioethanol fuels in concentration up to 85% by volume. The final aspect is especially topical for production of high quality high-octane fuel from low-octane hydrocarbon fractions, as well as maximum utilization of bioethanol octane-increasing potential. Currently VNII NP JSC is conducting research work aimed to develop production technology of E30 and E85 bioethanol fuels. This technology will enable the essential expansion of the potential of bioethanol application and the efficient resolution of usage of low-octane fractions due to production of high-octane fuel with improved ecological characteristics with a minimum possible cost. This article presents the developed technical requirements for bioethanol fuels E30, E85. © 2016 Elsevier Ltd

The possibility of producing diesel fuel for cold climates from middle distillates of different origin in the process of the catalytic dewaxing over zeolite catalysts with additions of iron is investigated. Introducing iron into the zeolite ensures the high stability of the catalyst. To mitigate the known disadvantages of the above process, a flowsheet with the separation of hydrogenate into fractions depending on the characteristics of the feedstock, followed by the dewaxing of the separated heavy diesel fraction and combining the resulting product with a light fraction that has the desired cold flow properties and does not require dewaxing, is proposed. The technical result of using this flowsheet in combination with any catalytic dewaxing process is the production of diesel fuel for cold and arctic climates that meets the requirements of GOST R (Russian State Standard) 52368-2005 and/or GOST R (Russian State Standard) 55475-2013 with minimized production costs. © 2015 Pleiades Publishing, Ltd.

Diesel fuels are developed and tested through the joint efforts of experts in the oil-refining industry, technology developers, and user organizations. The end result of comprehensive research and testing is the creation of normative documents for the production of new fuels. Diesel fuels UFS, RFS, andDZP are used as examples to show how problems encountered in optimizing the quality of diesel fuels were resolved. The extensive testing that these fuels underwent can no longer be done, which makes the collaborative efforts of specialists working in the field of chemmotology especially important. © 2014 Springer Science+Business Media.

The results of experimental studies on preparation of oil shale and oil residue blend for gasification to produce synthesis gas of the desired composition are reported. The feasibility of preparation of stable oil shale suspension in aqueous emulsion of high-viscosity residual fuel oil having structural-rheological characteristics that ensure unhindered pumping of gasification feedstock through the gas generator nozzle and uniform distribution in the combustion chamber is shown. © 2016 Springer Science+Business Media New York

Structural formation of plastic greases, which are essentially colloidal systems, during their fabrication and the factors that affect aging of lubricants during storage in containers and use in friction units are examined. The results of an analysis of the quality of the greases after prolonged use in friction units in different types of engineering are reported. © 2010 Springer Science+Business Media, Inc.

The physicochemical properties of heavy and super-heavy oils, problems and methods of processing oil residues and unconventional hydrocarbon stocks with high sulfur, metal, asphaltene, and resin contents are studied. The characteristics of catalytic and non-catalytic oil residue processing technologies are compared and ways of conversion of unconventional oils into synthetic oil are shown. The advantages of gasification of super-heavy residues, including in blend with solid fuels, with production of synthesis gas − a feedstock for oil chemistry and synthetic oil and hydrogen production − are analyzed. © 2015 Springer Science+Business Media New York
