上面两位翻译中还有不少问题！
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 ℃. |
