摘要
近年来石油(尤其是柴油)馏分脱除芳烃的问题受到越来越多的重视。目前研究较多的脱芳烃催化剂有负载型金属硫化物催化剂及负载型贵金属催化剂。后者的脱芳烃深度明显优于前者,但后者对原料中硫化物极为敏感,提高其抗硫性是该催化剂的研究重点。本文着重对改善贵金属芳烃饱和催化剂抗硫性的最新研究进行了综述。
Recently, aromatic saturation in distillate fractions specially in diesel fuel has received considerable attention. There are two major kinds of dearomatic catalysts, which are supported metal sulfide catalysts and supported noble metal catalysts. The latter is superior to the former in the depth of aromatic saturation, but it is sensitive to Scontaining compounds in feedstock. Recent progress in improving the sulfur resistance of noble metal aromatic saturation catalysts is reviewed in this paper.
