Application of Second Generation FCC Gasoline Selective Hydrogenation Technology

The second generation FCC gasoline selective hydrodesulfurization technology(RSDS -Ⅱ) was applied in SINOPEC Shanghai Petrochemical Company Limited.The first calibration result showed that sulfur content of RSDS -Ⅱproducts was less than 50μg/g,and RON loss was less than 1.0 unit with FCC gasoline(sulfur content of 460μg/g～470μg/g,and olefin content of 40%or so) as raw material.It was concluded that RSDS -Ⅱtechnology was an important technology for producing low - sulfur clean gasoline,as it had excellent desulfurization selectivity.
