摘　　要：在2.8 Mt/a重油催化裂化装置中,试应用了高加工负荷催化裂化催化剂(牌号为LMC-500),并与WP 3催化剂(美国Grace公司生产)的应用效果进行了对比分析。结果表明:在操作参数相近的条件下,当平衡催化剂含钒量约为7000μg/g时,与WP 3催化剂相比,使用LMC-500催化剂的汽油收率增加,柴油和干气收率呈下降趋势,焦炭收率略有增加,液化石油气中丙烯体积分数维持在40%,LMC-500催化剂表现出良好的重油转化能力和优异的目标产品选择性。The catalytic cracking catalyst with high processing load(LMC-500)was tried the ap-plication in a 2.8 Mt/a heavy oil catalytic cracking unit,the application effects between the LMC-500 and WP 3(produced by Grace Company)were com-pared and analyzed.The results showed that under the similar operation parameters,when the vanadium content of equilibrium catalyst was about 7000μg/g,compared with WP 3 catalyst,the yield of gasoline increased,the yield of diesel and dry gas decreased,the yield of coke increased slightly,the volume frac-tion of propylene in LPG remained around 40%using LMC-500 catalyst;LMC-500 displayed ex-cellent heavy oil conversion and outstanding target products selectivity.
