摘　　要：介绍了增产汽油SGC-1重油裂化催化剂在中国石化北京燕山分公司第二套重油催化裂化装置上的工业应用情况。结果表明,与空白标定时使用VRCC催化剂相比,在最大汽油产率方案、最大装置加工量方案和最大掺渣率方案下,汽油产率分别达到47.57%,47.05%,47.10%,分别增加了4.56,4.04,4.09百分点,干气、汽油和焦炭的选择性有所改善,尤其是汽油的选择性明显提高,总液体收率变化不大。SGC-1催化剂对增产汽油效果明显、对原料适应性好、干气选择性好,满足催化裂化装置改善产品分布的要求。The commercial application of FCC catalyst SGC-1for improving gasoline yield in the 2nd RFCCU of SINOPEC Yanshan Petrochemical Company was presented.The results show that the yield of gasoline increases to 47.57%,47.05%,and 47.10%,i.e.the growing range of 4.56,4.04,and4.09 percentage points,respectively for three solutions of maximizing gasoline yield,maximizing feedstock flow rate,and maximizing blending residue ratio.The selectivity of dry gas,gasoline,and coke are improved,especially the selectivity of gasoline increases significantly.While the yield of total liquid products remained steady.SGC-1catalyst has significant advances in increasing the yield of gasoline,good feedstock adaptability and dry gas selectivity.It can meet the requirement of improving product distribution of FCC unit.
