middle distillate

基本解釋

It was found that the Y-zeolite with lower total acid and higher L-acid ratio was beneficial to middle distillate selectivity and better activity.
結(jié)果表明，較低總酸量和較高L酸比例的Y分子篩有利于提高催化劑的中餾分選擇性，并保持較好的活性；
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.
由于原油重質(zhì)化和劣質(zhì)化的趨勢(shì)加劇，市場(chǎng)上中間餾分油需求日益增大，加氫裂化已成為發(fā)展較快的深度加工工藝。
The said catalyst can be used for hydrotreating process of fraction of petroleum, especially for hydrodesulphurization and hydrodenitrification process of middle distillate oil .
該催化劑可以廣泛的用于石油餾分的加氫處理過程，特別適合于中間餾分油的加氫脫硫、加氫脫氮和加氫脫芳過程。
