Influence of Mixing HLCO Diesel on Hydrogenation Characteristics and Product Distribution

The processing route and conversion technology of catalytic diesel oil were summarized and analyzed.The LCO light diesel oil and heavy diesel oil were extracted separately.Light diesel oil was hydrotreated as diesel fuel.The catalytic heavy diesel oil extracted from the first section of fractionating tower in the catalytic cracking unit was ring-opened by hydrogenation reaction and then converted into gasoline and liquefied gas by catalytic cracking reaction.The influence of different proportion of HLCO diesel oil mixed with wax-oil hydrogenation feedstock on the hydro-reaction characteristics and product properties of wax-oil was determined by pilot test.The results of industrial operation show that mixing 10%HLCO diesel oil with wax oil hydrogenation feedstock and mixing remaining LCO light diesel oil in diesel hydrogenation unit can not only solve the subsequent problems of catalytic diesel oil processing,but also reduce the ratio of diesel to gasoline and increase the output of gasoline and liquefied gas.
