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.

Catalysis in Industry | Year: 2015
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.

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
