Abstract

A process for preparing low-sulfur low-arylhydrocarbon clean diesel oil includes such steps as hydrorefining / hydrocracking raw hydrocarbon to obtain intermediate fraction oil, catalytic stripping to separate light fraction from heavy fraction, hydrorefining the light fraction to remove residual S and impurities, and catalytic stripping of heavy fraction for removing sulfure and arylhydrocarbon to obtain final product. Its advantage is cyclic use of two reactino segments for low cost.

Description

1. Technical field

[0001] The invention relates to a method for processing hydrocarbon raw materials to produce low-sulfur and low-aromatic clean fuels (especially clean diesel oil), more specifically, it is a hydrogenation process combination technology for converting hydrocarbon raw materials into low-sulfur and low-aromatic fuels . 2. Background technology

[0002] As we all know, with the rapid development of the transportation industry and the automobile industry worldwide, the demand for diesel for vehicles increases rapidly. At the same time, the control of automobile exhaust emissions in the new environmental protection regulations has higher and higher requirements on the quality of diesel oil. In particular, the "World Fuel Specifications" published in 1997 has strict requirements on the sulfur content, cetane number, and aromatic content of diesel oil (including polycyclic aromatic hydrocarbon content) and density, etc. have put forward more stringent requirement...
