【摘要】 油品中含硫化合物所产生的危害是多方面的,特别是近年来车用燃料尾气排放的二氧化硫对环境造成的负面影响更引起了人们的关注。发达国家纷纷制定环保法规严格限制油品中硫的质量分数,因此,讨论各种脱硫技术对我国炼油工业具有重要意义。介绍了当前轻质油品脱硫的一些方法,包括传统的加氢脱硫和吸附脱硫等。着重对基于氧化反应的几种脱硫技术,如CED,ASR-2,超声波脱硫,光氧化法脱硫等进行了介绍,同时对烷基化脱硫,沉淀脱硫等方法也给予了简介。与传统的加氢脱硫方法相比,各种非加氢脱硫方法将会得到更大的发展。更多还原

【Abstract】 Sulfides in oils can lead to harms in all kinds of aspects, especially the deterioration to the environment produced by the sulfur dioxide. The developed countries make the environment regulation to limit the sulfur content, so it is very significant for our refining industry to discuss various desulfurization technology. Some methods of desulfurization for the light oil were described, including hydrodesulfurization and adsorptiondesulfurization. The main focus was put on oxidation desulfurization, for example, CED technology, ASR-2 technology, ultrasound desulfurization and photochemical desulfurization. In addition, methods of desulfurization by alkylation and precipitation were also discussed. Compared to the traditional hydrodesulfurization, all kinds of non-hydrodesulfurization will get great development.更多还原
