Abstract

The invention relates to the technical field of waste oil comprehensive utilization and fuel oil processing, particularly to an automatic continuous production process for producing diesel oil with waste oil through a catalytic cracking method. The production process comprises the following process steps: 1, the waste oil is pretreated; 2, the pretreated waste oil is subjected to hot cracking and catalytic cracking, so as to obtain crude oil, wherein the catalytic cracking comprises liquid-phase catalysis and gas-phase catalysis; 3, the crude oil is fractionated; and 4, the finished product is obtained through refining and filtering. The invention has the advantages that gelatine, asphaltene, sulfide, oxide, unsaturated hydrocarbon and the like can be well removed, so that the finished oil is clear and transparent, has a pure smell, and cannot deteriorate after being stored for a long time; viscosity and pipeline blockage are avoided in the production process, the production process is simple, the conditions are easy to control, the investment is low, the results are quick, the efficiency is high, the use is simple, and the operation is convenient.

Description

technical field [0001] The invention relates to the technical field of comprehensive utilization of waste oil and fuel oil processing, in particular to an automatic continuous production process for regenerating diesel oil from waste oil by catalytic cracking method. Background technique [0002] Oil supply is becoming increasingly tight, prices are rising, and resources are becoming increasingly depleted. There are signs that the era of low oil prices may be gone forever. In order to alleviate the shortage of oil supply, make full use of energy resources, save energy, reduce pollution, and turn waste into treasure has become a basic national policy of the country. Make full use of waste raw materials, especially waste oil, to regenerate light and heavy diesel oil and fuel oil through catalytic cracking. etc. It can not only alleviate the contradiction between supply and demand of my country's oil shortage and increasing demand, but also promote environmental protection and t...
