摘　　要：加氢脱硫是一种比较成熟的生产工艺,已在原油精制中普遍使用了多年。随着原油质量变差和更严格的环境法规的应用(例如,需要降低燃料中的硫含量),人们对该工艺不断更新。在实现燃料低硫水平方面,特别重要的是一类特殊化合物如:二苯并噻吩、4-甲基二苯并噻吩和4,6-二甲基二苯并噻吩所造成的受阻问题。在使用现有催化剂加氢精制时,二苯并噻吩表现出抗加氢脱硫的能力。本文综述了关于加氢脱硫工艺中有关高位阻含硫分子脱硫的研究状况。Hydrodesulfurization is a well-documented process which has been commonly used in the refining of crude oil for several years.It is a process for which interest is frequently renewed due to the requirement to use Deteriorating crude oil and the application of more severe environmental legislation,for example,the need to reduce sulfur levels in fuels.Of particular importance in achieving low sulfur levels in fuels is the problem posed by a particular class of compounds,namely hindered dibenzothiophenes,e.g.dibenzothiophene,4-methyldibenzothiophene and 4,6-dimethyldibenzothiophene.Dibenzothiophenes demonstrate resilience to hydrodesulfurization using current catalyst formulations.This overview addresses the key area of hydrodesulfurization chemistry concerning the desulfurization of highly hindered sulfur containing molecules.
