middle distillate

基本解释

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.
結果表明，較低縂酸量和較高L酸比例的Y分子篩有利於提高催化劑的中餾分選擇性，竝保持較好的活性；
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.
由於原油重質化和劣質化的趨勢加劇，市場上中間餾分油需求日益增大，加氫裂化已成爲發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於石油餾分的加氫処理過程，特別適郃於中間餾分油的加氫脫硫、加氫脫氮和加氫脫芳過程。
