DEVELOPMENT AND APPLICATION OF RLG TECHNOLOGY FOR LCO SELECTIVE HYDROCRACKING TO PRODUCE HIGH-OCTANE GASOLINE OR LIGHT AROMATICS FEEDSTOCK

On the basis of analyzing the aromatic composition of FCC typical light cycle oil（LCO ）and the high-octane components in gasoline fractions, combined with aromatic hydrocarbons hydrocracking reaction mechanism, the optimal chemical reaction path of RLG technology （LCO selective hydrocracking to droduce high-octane gasoline or light aromatics was determined. The effects of RLG process conditions on product yield and property were studied. The application of the first generation RLG technology showed that using the LCO with density greater than 928.1 kg/m³ as raw material, the RLG technology could produce the gasoline with the average yield more than 43.48%, sulfur content less than 1.3μg/g and RON more than 92.0. Besides that, this technology could also produce clean diesel. The RLG-Ⅱ technology was developed on the basis of the first-generation RLG technology. The pilot tests results on raw oil adaptability medium-scale showed that the RLG-Ⅱ technology had good adaptability to various types of LCO. The product gasoline with high yield and high-octane number and the clean diesel blending component of low sulfur and low nitrogen could be obtained.
