LRC-99与LDO-75催化剂在催化裂化装置上应用对比分析

PERFORMANCE COMPARISON OF LRC-99 AND LDO-75 CATALYST IN FCC UNIT

对尼日尔炼油厂催化裂化装置使用LRC-99增产柴油催化剂和LDO-75催化剂期间的运转情况及产品分布进行了分析和对比。结果表明:与使用LDO-75催化剂时相比,使用LRC-99催化剂后,柴油收率提高1.52百分点,汽油收率降低0.84百分点,轻质油收率提高0.68百分点,表明LRC-99催化剂比LDO-75催化剂具有较高的增产柴油性能和更高的经济效益;LRC-99催化剂比LDO-75催化剂具有更强的抗磨性能和抗重金属污染能力,在原料中Ni质量分数为22.55μg/g、平衡剂上Ni质量分数接近15 000μg/g的情况下,催化裂化装置仍具有较好的产品分布。

The performance of LRC-99 catalyst for increasing diesel and the LDO-75 catalyst for increasing gasoline in Niger refinery FCC unit was introduced. The results show that the LRC-99 catalyst increases the total yield of light oil by 0.68 percentage points （diesel yield increases 1.52 percentage points, gasoline reduces 0.84 percentage points）, indicating the ability of increasing diesel production of the LRC-99 catalyst. It is found that LRC-99 also has stronger anti-wear and anti-pollution by heavy metal than LDO-75 catalyst. At Ni content of 22.55 μg/g in feed and 15000μg/g on equilibrium catalyst, FCC unit using LRC-99 catalyst still provides a better product distribution.
