Abstract: The commercial application of SLG-1 catalyst for LTAG technology in the 3rd MIP-CGP unit of SINOPEC Shijiazhuang Refinery & Chemical Company was presented. The results showed that the yield of gasoline increases 4.00 percentage points (from 46.79% to 50.79%), octane-barrel increases by 3.46, the yields of LCO and dry gas decrease, while total liquid yield increases by 2.17 percentage points. SLG-1 catalyst showed significant advances in increasing bottoms cracking and improving the conversion of hydrotreated LCO.
