A method and system for preparing light aromatic hydrocarbons |
| abstract |
The present invention relates to a hydrocracking method and system for producing high-quality light aromatic hydrocarbons. It mainly solves the problem that the purity of aromatic hydrocarbons is not high when the prior art takes aromatic hydrocarbons as target products. In the present invention, hydrocracking reaction is carried out after the catalytic diesel stream is subjected to hydrorefining, separation of impurities and deep denitrification. After the reaction, fractions including light hydrocarbons, heavy naphtha rich in light aromatic hydrocarbons and heavy tail oil are obtained by separation. The invention can be used to produce heavy naphtha containing high-quality light aromatics from catalytic diesel, solves the problem of low purity of aromatics in hydrocracking products of catalytic diesel, and achieves good technical results. |
