3.The catalytic activity and selectivity for hydrodesulfurization(HDS) and hydrodenitrogenation(HDN) were studied by using benzothiophene(BT), dibenzothiophene(DBT) and quinoline as model compounds.
实验结果表明,升高反应温度和压力均提高催化剂的加氢脱硫、加氢脱氮活性;
4.Glutamic acid fermentation is a kind of biochemistry fermentation engineering.Its selectivity is undivided comparatively.It is oxybiotic fermentation and is strict to air quality.
谷氨酸发酵是一种对发酵菌种选择性比较专一的生化发酵工程,且性发酵。
5.Cyanopyridine,intermediate of rimifon, was synthesized from 4-picoline using vanadium oxide as a catalyst in a fixed-bed reactor, reached 99% conversion of 4-picoline, 88% selectivity and 87.
