Abstract

The invention provides a gasoline and a preparation method thereof. The preparation method comprises the following steps: 1, carrying out physical desulphurization and denitrification treatment on direct coal liquefaction naphtha to obtain a purified product; 2, fractioning the purified product to obtain a C6- product and a C7+ product; 3, carrying out a reforming reaction on the C7+ product to obtain mixed aromatic hydrocarbons, and separating the mixed aromatic hydrocarbons to obtain a reformed gasoline blend product; and 4, mixing 40-51 parts by weight of the reformed gasoline blend product, 20-35 parts by weight of mixed C5 and 20-30 parts by weight of the C6- product to obtain the gasoline. A physical desulphurization and denitrification technology adopted in the invention has the advantages of simple operation, low cost and low energy consumption. The reformed gasoline blend product, the mixed C5 and the C6- product are mixed according to a specific weight ratio, so increase of the octane number of the gasoline is facilitated, and the vehicle gasoline produced in the invention has the advantages of low emission, high calorific value and high quality.

Description

technical field [0001] The invention relates to the field of coal chemical industry, in particular to a gasoline and a preparation method thereof. Background technique [0002] With the depletion of the world's limited oil resources and the increasing awareness of environmental protection, research and search for environmentally friendly alternatives to oil energy have become one of the directions of world technology development. Biomass and coal conversion technology is one of the important ways to diversify the solution to the shortage of petroleum resources, and it has become the consensus of experts and scholars. Coal is converted into oil or other chemical products through direct liquefaction reaction. On the one hand, it can solve the shortage of oil resources and meet the energy demand of the rapid growth of the national economy; environmental pollution. [0003] Coal-to-naphtha is divided into direct coal liquefaction naphtha and coal indirect liquefaction naphtha....
