Production of motor benzene via plastic processing as perspective direction of "green" fuel power industry

Abstract

The paper reviews the topicality and practical significance of the implementation of processing technology of plastic with the purpose of obtaining raw material for manufacturing motor benzene. It is shown that this case is the advantageous strategy for the damage reduction to the environment from the oil-gas complex and usage of commercial gasoline based on the fossil hydrocarbon crude and for the utilization of plastic wastes as well. The perspective technologies of plastic processing including pyrolysis, catalytic cracking, hydrothermal liquefaction based on the bibliographic review and the recommendations on the improvement of benzene component obtained as a basis for industrial production of motor benzene are presented. In the capacity of the last ones, the implementation of alcohol mixed octane-increasing additives based on the ethanol is justified. It is shown that using alcohol not only increases octane number of the fuel, but also saves expensive hydrocarbon components, allows reducing the toxic high-octane aromatic hydrocarbons in the gasoline, improves the distribution of octane numbers by benzene fractions based on the reformat, as well as expands the crude base for fuel production due to the non-oil raw. The studies showed that adding 10 % of alcohol is the optimum concentration, as on the one hand it provides the growth of knock characteristics and phase stability of the gasoline, on the other hand does not require additional regulation of motor engine for using such fuel.
