摘要
以AEL分子筛为载体,制备出一种贵金属异构脱蜡催化剂;以n-C12为模型物,以大庆炼化加氢预精制后的650SN糠醛精制油为实际原料考察该催化剂的加氢异构化性能。结果表明,所制备的异构脱蜡催化剂对n-C12以及650SN糠醛精制油均具有良好的异构化活性和选择性,其性能优于国外同类参比剂,加工650SN糠醛精制油时,可高收率地生产优质APIⅢ类润滑油基础油,目标产品倾点为-21℃,比采用参比剂时低6℃,重质基础油收率为62.79%,比采用参比剂时高5.55百分点。
A hydroisomerization catalyst was developed based on AEL zeolite.n-C12 and the hydrotreated 650 SN furfural refined oil were used as feeds,respectively,to evaluate the hydroisomerization performance of the catalyst.The results show that the catalyst has better hydroisomerization activity and selectivity.When processing 650 SN,the high quality group APIⅢ lube base oil is produced.The pour point of the base oil reaches-21℃,6℃lower than the reference catalyst,and heavy base oil yield reaches 62.79%,5.55% higher than the reference one,which indicates that the hydroisomerization performance of the catalyst is better than the reference catalyst.
