Abstract
Regularities of distribution of sulfur compounds and hydrocarbons on fractions of catalytic cracking gasoline are considered. Need of carrying out purification of gasoline of catalytic cracking before its use as a component of commercial gasoline is shown. The essence of modern technologies of a hydrotreating of catalytic cracking gasoline is considered. Consistent patterns of change of properties of catalytic cracking gasoline of MSCC process (UOP) before and after its hydrotreating through the Prime G+ process (Axens) are determined. Features of change of hydrocarbonic composition of catalytic cracking gasoline as a result of its hydrotreating through the Prime G+ process are revealed. The hydrocarbonic composition of the light and heavy gasolines received in the course of a hydrotreating of catalytic cracking gasoline through the Prime G+ process is studied. The reasons of decrease in octane number of catalytic cracking gasoline of MSCC process in the course of its hydrotreating through the Prime G+ process are established.
