Abstract

The invention discloses a method and system for producing diesel oil from an inferior oil material. The method includes the steps: mixing the inferior oil material with waste plastics, then carrying out a pyrolysis reaction, then making an obtained pyrolysis gas contact with a catalyst and carrying out a catalytic reaction, separating the obtained catalytic reaction product to form a gas-phase product and a liquid-phase oil product, and hydrotreating the liquid-phase oil product to form naphtha and diesel oil. The obtained naphtha can go to an ethylene-removing cracking unit to be used as a cracking raw material, and the obtained diesel oil can be used as a qualified diesel oil product and leaves factories. The method has the advantages of simple process and cheap and easily obtained raw materials, can make full use of the waste plastics, the inferior oil material and other resources, and also is green and environmentally friendly; and the yield of light fuels can reach more than or equal to 95%, and the obtained diesel oil has good quality.

Description

technical field

[0001] The invention particularly relates to a method and a system for producing clean fuel oil by using inferior oil and waste plastics through thermal cracking / catalysis / hydrogenation combined process. Background technique

[0002] At present, the world's oil resources are increasingly scarce and the price is increasing, but petrochemical products such as waste oil or refinery by-products (such as ethylene tar) are not effectively utilized. In addition, with the improvement of people's living standards, the demand for clean fuels and other growing. The existence of these contradictions makes it of great practical significance to convert the aforementioned waste oil or refinery by-products to obtain clean fuel oil.

[0003] Taking ethylene tar as an example, it belongs to the high-temperature condensation product of ethylene cracking raw materials and products in the steam cracking process. Its initial boiling point is 170-260°C, and its final boiling point...
