摘　　要：SKI-210脱乙基型C 8芳烃异构化催化剂在中国石化上海石油化工股份有限公司大型芳烃联合装置上实施了首次工业应用。催化剂生产过程可控,成品质量稳定,应用开工顺利,运行状况良好。性能考核结果表明,催化剂二甲苯异构化活性达到23.53%,乙苯转化率达到68.33%,单程二甲苯损失率为1.37%,性能达到合同要求,满足用户生产需求。与上一代催化剂相比,SKI-210催化剂的活性和选择性同时得到提高,实现了催化性能整体技术进步。The ethylbenzene dealkylation type of C 8 aromatics isomerization catalyst SKI-210 was first commercialized in a large integrated aromatics complex.The catalyst preparation process was controllable with good finished product quality.Using the catalyst,the aromatics complex was started up smoothly with super performance during actual long period operation.The test results of application showed that the isomerization activity(PX X)of the catalyst was 23.53%and the ethylbenzene conversion was 68.33%while the xylene loss per pass was 1.37%.The catalyst performance can meet the contract and user’s production requirements.Compared with the last generation catalyst,the activity and selectivity of SKI-210 catalyst were both improved to achieve the overall technological progress of catalytic performance.
