炼化一体化项目中催化汽油加氢脱硫工艺路线选择的研究

Study on the selection of catalytic gasoline hydrodesulfurization process route in refining and chemical integration project

目前随着节能减排和环境保护日益突显,对新建的炼化一体化项目中车用汽油质量要求越来越严格。催化汽油是汽油的主要馏分油,占汽油池总量的60%以上,因此汽油中的硫80%~90%来自催化汽油,降低催化汽油硫含量是降低产品汽油中硫含量的关键。

At present,with the increasing importance of energy conservation,emission reduction and environmental protection in the world,the quality requirements of automotive gasoline in the newly built integrated project of refining and chemical are more and more stringent.Catalytic gasoline is the main distillate of gasoline,accounting for more than 60%of the total amount of gasoline pool,so 80-90%of the sulfur in gasoline comes from catalytic gasoline,reducing the sulfur content of catalytic gasoline is the key to reduce the sulfur content of product gasoline.
