新型抗钒催化剂CGP-1YZ在MIP装置上的工业应用

介绍了增强抗钒能力的重油裂化催化剂CGP-1YZ在中国石化扬子石化有限公司2号催化裂化装置上的应用情况。催化剂CGP-1YZ中含有高活性稳定性的分子筛及钒捕集组元,能够有效抑制原料油中钒对催化剂的破坏;在完全再生操作模式下,平衡剂上钒质量分数达到1%时,催化剂CGP-1YZ依然具有较好的综合性能。与空白标定结果相比,中期标定结果显示液化气和汽油收率分别增加了3.93和5.64百分点。

COMMERCIAL APPLICATION OF NOVEL ANTI-VANADIUM CTALYST CGP-1YZ IN MIP UNIT

CGP-1YZ is a FCC catalyst with enhanced anti-vanadium ability. The commercial application of the catalyst in 2# FCC unit of Yangzi Petrochemical Co. Ltd. was introduced in this paper. CGP-1YZ catalyst integrated the zeolite with high activity and stability, and vanadium trapping component, which made the catalyst prevent the deactivation by vanadium in the feed effectively. Under full-regeneration conditions, when the vanadium content on the equilibrium catalyst reached 1%, CGP-1YZ catalyst still showed better overall performance. Compared with the case of blank calibration, better product distribution was obtained in mid calibration period, and the LPG and gasoline yield increased 3.93 and 5.64 percentage points, respectively.
