中文摘要：

汽油深度脱硫的关键是在脱硫同时避免辛烷值的下降和汽油收率的损失;柴油深度脱硫的关键是对反应活性最低的4,6-二甲基苯并噻吩类化合物中硫原子的脱除,并克服原料中多环芳烃和含氮物以及产物中H2S对脱硫效果的抑制作用。本文概述了汽油和柴油深度脱硫催化剂在工业应用方面的研究进展,综述了加氢脱硫催化剂基础研究方面的最新动态;强调了在分子和原子水平上认识加氢脱硫催化剂微观结构和反应机理对研发超高活性及选择性深度脱硫催化剂的指导作用。

英文摘要：

For the deep desulfurization of gasoline,it is crucial to avoid the decreases of octane number (RON) and final gasoline yield; for the deep reduction of sulfur content in diesel oil,the major difficulties are how to remove sulfur from inactive compounds like 4,6-dimethyldibenzothiophene (4,6-DMDBT) and at the same time to conquer the inhibiting effects of polyaromatics and nitrogen compounds in the feed as well as H2S produced during the desulfurization. In this paper,the progresses of the development of de...
