摘要
采用FIDW 1催化剂分别对一种VGO溶剂脱蜡油加氢处理尾油、一种减三线油和一种减压渣油丙烷脱沥青油糠醛精制油的加氢处理尾油和一种VGO加氢处理尾油进行了异构脱蜡试验。结果表明 ,该催化剂具有良好的脱蜡异构活性、选择性 ,可以生产高粘度指数润滑油基础油馏分 ,副产物主要是优质的喷气燃料和柴油馏分。与催化脱蜡和溶剂脱蜡相比 ,异构脱蜡具有基础油收率高、粘度指数高、副产品价值高等优点。
Isodewaxing experiments were carried with several kinds of hydrogenation unconverted oil over FIDW 1 catalyst. The hydrogenation feedstocks were a solvent dewaxing oil from VGO, a third cut of vacuum column, a furfural extraction raffinate of vacuum residue deasphalted oil, and a VGO. The results indicated that the said catalyst had high isomerization activity and selectivity. In comparison with conventional catalytic dewaxing and solvent dewaxing, the isodewaxing showed the advantages of high yield of base oil with high viscosity index as well as high value by products.
