Two-step super-depth method for removing arenes from natural gas synthetic oil

Abstract

This invention relates to a method for super-deep removing aromatics in two steps from natural gas synthetic oil, in which, a natural gas synthetic oil raw material and H enter into a first fixed bed reactor at the same time to contact and react with a hydrofining catalyst, the reacted substance from the first reactor enters into a second fixed bed reactor directly to contact and react with an aromatic saturated catalyst to get a gas-oil mixture to be separated and fractionated to get the target product, the gas with rich H is used circularly by a circulating compressor.

Description

technical field

[0001] The invention relates to a method for refining hydrocarbon oil with hydrogen, more specifically, the present invention is a method for refining natural gas synthetic oil through hydrogenation. Background technique

[0002] In the 21st century, the world's oil refining industry is facing the crisis of the gradual depletion of oil resources and the dual pressure of using environmentally friendly processes to produce clean fuels. The natural gas-to-liquids technology that can meet the challenges of increasingly stringent environmental regulations is emerging as a way to efficiently utilize natural gas. Become a new way to produce clean fuel in the new century.

[0003] Fractions such as kerosene and diesel oil obtained after converting natural gas into synthetic oil by Fischer-Tropsch synthesis process must undergo corresponding hydrotreating and upgrading to become liquid fuels that meet the requirements of engines. The process of natural gas to synthet...
