RESEARCH PROGRESS IN LCO CATALYTIC CONVERSION TO PRODUCE HIGH VALUED PRODUCTS

Abstract

Abstract: It is an important way to seek high value-added conversion technology in accordance with the resource endowment of FCC diesel (LCO) to solve the problem of over-capacity of diesel and to widen the source of light aromatics. The LCO conversion process based on different technical routes was introduced，and the effects of raw material properties，molecular sieve types and operating conditions on the performance of hydrogenated LCO catalytic conversion to produce high value-addedd products were described in detail. At the same time，it was pointed out that LCO conversion technology had great petential for improvement in producing light aromatics，and LCO hydrotreating-catalytic cracking process could give full play to the advantages of catalytic cracking reaction system. At present，the understanding of the conversion law of hydrogenated LCO is still limited to the full fraction，so it is necessary to deepen the understanding of the law of hydrogenated LCO's narrow fraction，components and the catalytic cracking reaction of key model compounds.

Key words: FCC lighe cycle oil, hydrocracking, hydrotreating, gasoline, aromatics
