According to the analysis of table 1, the catalyst has well hydroisomerization activity and adaptability to the feedstocks, whcih can effectively transform various waxy feedstocks  into low-freezing base oil with high or ultrahigh viscosity index. The efficiency of the reaction relates to the wax content. As naphthenic VGO and 200SN dewaxing oil contain little wax, the condensation point of each is not high, and it can reduce the pour point to the prescriptive temperature under a milder condition. While the wax content of 650SN is higher, the pour point must be reduced by 80 ¡æ, so it needs a rigorous reaction condition.

    As shown in table 1, the catalyst  has £¨preferable£© hydroisomerization activity and adaptability to the feedstocks, over which various waxy feedstocks can be efficiently converted to low-freezing base oils with high or ultrahigh viscosity index. The reaction efficiency is dependent on the wax content of the feedstock. As naphthenic VGO and 200SN dewaxing oil possess rather low wax content and pouring points, the pour point could be reduced to the prescriptive temperature under a milder condition. Contrarily, because the wax content of 650SN is high, critical reaction conditions were required to reduce the pour point of 650SN by 80 ¡æ.
