CATALYSTS FOR CATALYTIC CRACKING OF HEAVY REFINERY RESIDUES

Abstract

The purpose of this work is to develop the oil refining and petrochemical industry of the republic by increasing the depth of processing of heavy oil residue - fuel oil, obtained in the process of refining oils at the atmospheric distillation unit of the oil refinery. At present, the oil refining industry of Uzbekistan faces the task of complex processing of hydrocarbon raw materials, increasing the depth of processing and the yield of light oil products. In this regard, it is important to solve the problem of shortage of raw materials for oil refineries of the Republic of Uzbekistan. The problems of the possibility of modernizing catalytic cracking process units by including the process of hydrodesulfurization of raw materials were considered, as a result of which the quality and yield of light products are increased when using fuel oil and secondary semi-finished products containing a large volume of various sulfur compounds.
