Problems solved by technology

It is difficult to compete with regular petroleum products because of oil regeneration or waste oil regeneration diesel and fuel oil quality is difficult to control, or the quality is not up to standard or environmental protection problems, or the performance of the product itself is not good.
[0006] There have been some reports on the production of diesel or fuel oil from waste oil, but none of these methods, processes or devices has completely changed the waste discharge, environmental pollution, complex process, high production cost, time-consuming, Disadvantages such as energy consumption, there are more or less such problems

Abstract

The invention relates to the technical fields of waste oil comprehensive utilization and fuel oil processing, and in particular relates to a double crack double catalysis new process used for generating diesel oil crude oil by utilizing waste oil. Firstly a gas phase catalyst is loaded into a gas phase catalysis tower, then a mixture of pre-treated waste oil and a liquid phase catalyst in a ratio of 100: (0.1-0.2) sequentially passes through a cracking reactor and a gas phase catalysis tower, waste oil is catalytically cracked at the temperature of 350-550 DEG C, and crude oil similar to diesel oil molecular structure is formed, wherein molecular weight is reduced to be about 230 from about 1000. In the new process provided by the invention, the raw materials are only required to be thrown into a reactor, mineral oil or grease macromolecular can be catalytically cracked under the action of a special catalyst, a molecular structure similar to diesel oil is formed, the molecular weight is reduced to be about 230 from about 1000, and the molecular weight is basically equivalent to the diesel oil.

Description

technical field [0001] The invention relates to the technical fields of comprehensive utilization of waste oil and fuel oil processing, in particular to a new double-cracking and double-catalyzing process for regenerating diesel crude oil from waste oil. 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 turn waste int...
