茂名石油化工公司炼油厂Ⅱ套催化裂化装置近年加工国外原油比例加大,原料油中钒含量上升,催化剂钒污染严重,产品收率和产品质量受到严重的影响。试用LV—23抗钒催化剂后,产品收率、掺渣比均有所提高,催化剂消耗有所下降。平衡剂钒含量保持在4000～5000ppm的水平上,催化剂仍能保持较高的活性。 Maoming Petrochemical Company Refinery Ⅱ set of catalytic cracking unit in recent years, the proportion of processing of foreign crude oil increased, the feedstock of vanadium content increased, vanadium catalyst serious pollution, product yield and product quality are seriously affected. Trial LV-23 anti-vanadium catalyst, the product yield, slag ratio have increased, the catalyst consumption decreased. Balance of vanadium content remained at 4000 ~ 5000ppm level, the catalyst can still maintain a high activity.
