摘要
本文介绍了一种含有中孔硅铝磷分子筛(SAPO-11)和贵金属组分的双功能异构脱蜡催化剂,该催化剂可以由含蜡的加氢裂化尾油生产粘度指数120以上的VHVI润滑油基础油馏分,而且不需要溶剂脱蜡。
A twoway isodewaxing catalyst containing an mediumpore silicoaluminophosphate molecular sieve (SAPO11)and noble metal components was developed.A VHVI lubricating base oil fraction with Viscosity Index of over 120 can be produced over this catalyst through isodewaxing of waxy hydrocracking tail oil,thus eliminating solvent dewaxing process.Influence of operating conditions on performance of the catalyst was also studied.
