Abstract
In the article, a new processing technology is presented in the «Hydrocracking of heavy oil residues» (SPR-1) unit with the presence of highly dispersed aluminosilicate catalysts suspended in fuel oil. The hydrocracking process of fuel oil obtained from Baku oils was studied with the participation of catalysts modified by means of ion exchange and impregnation methods of Az-4 mineral. The main results of the study on the production of gasoline fraction by hydrogenation of heavy oil residues under low pressure with the presence of purchased catalysts are presented.It was determined that under optimal conditions 6% of fuel oil hydrocracking without catalyst; 26% with 2.5% Az-4 addition. When Az-4 catalyst modified with Ni and Mo by impregnation and ion exchange methods is used, the yield of gasoline fraction is 32 and 34.45% by mass, respectively. It was shown that the amount of sulfur, unsaturated hydrocarbons and iodine in the gasoline fraction decreased. The octane number increases from 64 to 71.The composition and properties of the obtained gasoline fraction were studied by NMR and IR spectroscopy methods.
