摘要
以SAPO-11和SAPO-31分子筛为载体,负载Pt金属,制备出Pt/SAPO-11和Pt/SAPO-31加氢异构脱蜡催化剂。以正十二烷(n-C12)作为模型化合物,以预精制后的200SN酮苯脱蜡油为实际原料,考察了2种催化剂的加氢异构化性能。结果表明,以n-C12为原料,在达到最高异构体收率时,Pt/SAPO-31催化剂的反应温度较Pt/SAPO-11催化剂低30℃,异构体收率较Pt/SAPO-11催化剂高19.7%;以预精制200SN酮苯脱蜡油为原料时,在反应条件相同和产品性质相当的情况下,Pt/SAPO-31+工业催化剂组合催化剂获得的中质基础油收率为82.03%,比Pt/SAPO-11+工业催化剂组合催化剂高2.4百分点。
Two precious metal hydroisomerization catalysts were developed based on SAPO-11 and SAPO-31 molecular sieves. The n-C12 and hydrotreated 200SN benzol-ketone dewaxing oil were used as feeds, respectively, to evaluate the hydroisomerization performance of the catalysts. The results showed that Pt/SAPO-31 exhibited better catalytic performance than Pt/SAPO- 11 . When processing n-C12,the reaction temperature of Pt/SAPO-31 was 30℃ lower than Pt/SAPO- 11 at the isomer in the highest yield, and the isomer yield of Pt/SAPO-31 was 19. 1% higher than Pt/SAPO-11. When processing hydrotreated 200 SN benzol-ketone dewaxing oil, the medium base oil yield which acquired by Pt/SAPO-31 and industrial catalysts combined catalyst reached 82. 03 % , 2. 4 percent higher than the Pt/SAPO-11 and industrial catalysts combined catalyst at the same reaction conditions and product properties.
