the hydrocracking process is now in rapid development as the crude oil becoming heavier and poorer in quality and the demand of middle distillate becoming larger.
the diesel fuel includes a major amount of middle distillate fuel;
柴油机燃料包括大量的中间馏分燃料;
the said catalyst can be used for hydrotreating process of fraction of petroleum, especially for hydrodesulphurization and hydrodenitrification process of middle distillate oil .
moreover, there is disclosed a method for improving the average film thickness from the combustion of a middle distillate fuel in a compression ignition engine.
此外,公开了在压缩点火发动机中改进来自中间馏分燃料燃烧的平均膜厚度的方法。
the initial operation show that the unit is stable in operation, high in middle distillate yield, good in product quality and low in energy consumption.
