Lashkhi V. L. (Firm “NAMI-CHEM” JSC, Moscow)
Keywords: chemmotology, development, prospects.
Abstract. The current state of chemmotology and the prospects for its development for the future are analyzed. It is noted that in terms of methodology and in terms of the level
of professionalism of researchers, today’s chemmotology is far from the state of the 1970–1980s. The current situation needs a radical change.

OIL REFINING: TECHNOLOGY, PROCESSES
Zyikov A.V., Kapustin V.M. (Gubkin Russian State University of Oil and Gas, Moscow)
Keywords: gas fractionation, butane, isobutane, energy efficiency of technological fractionation schemes.
Abstract. The authors of the article assesses the classical fractionation schemes of refinery gases into individual components in order to find options for upgrading technological schemes of installations to reduce energy consumption and increase the production of individual hydrocarbons such as isobutane and butane of normal structure contained in refinery gases. The implementation of solutions for the modernization of the technological scheme of the gas fractionation plant will increase the production of isobutane for the production of a valuable component of automobile gasoline – alkylate. In turn, increasing the energy efficiency of the process has a positive effect on the economics of the process of isomerization of butane of normal structure into isobutane, in order to expand the resource base of the alkylation process.

Keywords: gasoline, high-octane components, methyl tert-butyl ether, isopropyl alcohol, isobutyl alcohol, isopropylbenzene, octane number, fractional composition.
Abstract. The article provides an analysis of the Russian market for motor gasoline and methyl tert-butyl ether. It has been revealed that there is a significant growing demand for high-octane components and existing restrictions on the production of the highest-tonnage of them (MTBE), which leads to market scarcity and rising prices. A list of promising alternative high-octane components has been determined, the most effective of which are bioethanol, APDC 3014 and N-methylaniline. Based on an expanded set of potential high-octane components and taking into account the characteristics of their fractional composition and octane-increasing characteristics, various experimentally substantiated optimal options for the composition of unleaded AI-92 gasoline have been developed, both corresponding to class K5 according to GOST 32513-2013, and promising ones with a high oxygen content (up to 3. 7% wt.).
