【 摘 要 】

Because hydrotreating (HDT) of FCC gasoline is one of the important processes used to prepare such gasoline forblending, the development of a catalyst for this process is of great interest. Currently, the industrial HDT of FCC gasoline consists of two stages and the creation of a new catalyst for one-stage HDT will make this process more efficient. Recently, ourgroup has developed the CoMo/Al2O3-ASA catalyst and studied the influence of Si/Al ratio on the target reactions of HDT process. Despite the high selectivity and activity, the catalyst with ASA is not applicable in industry because of its low strength. Thepresent work moves forward to study the influence of the ASA content in the catalyst support and clarify the possibility todevelop the catalyst that combines high activity and selectivity in HDT reactions with successful performance. Here we show thatthe CoMo catalyst with ASA/Al2O3 molar ratio 1/1 in the support is the best combination for FCC gasoline hydrotreatment due toexceptional properties of the catalyst composition.
