The FCC naphtha selective hydrodesulfurization technology (RSDS-II) has been tested with different feedstocks in pilot scale. The results show that RSDS-II technology is viable in terms of its adaptability to different feedstocks. To pro- duce gasoline with a sulfur content of less than 50 μg/g by the RSDS-II technology, the gasoline RON loss is less than 1.8, 0.9 and 0.2 units, respectively, upon processing the conventional high-sulfur and high-olefin FCC naphtha, the high-sulfur MIP naphtha, and the medium-sulfur or low-sulfur MIP naphtha. Upon using the naphtha produced from pre-hydrotreated FCC feedstock as the RSDS-II feedstock to manufacture gasoline with a sulfur content of lower than 10 μg/g, the RON loss does not exceed 1.0 unit. The RSDS-II technology has been commercialized successfully at many refineries. The result of operat- ing commercial RSDS-II unit at the Shanghai Petrochemical Company has revealed that upon processing a feedstock con- taining 38.7 v%—43.3 v% of olefins and 250 —470 mg/g of sulfur, the sulfur content in the treated gasoline ranges from 33 μg/g to 46 μg/g and the RON loss is equal to only 0.3—0.6 units. Till now this RSDS-II unit has been operating smoothly over 30 months. Thanks to its high HDS activity and good selectivity, the RSDS-II technology can meet the refinery's needs for adequate upgrading of gasoline.
