Problems solved by technology

[0009] In addition to the target products (gasoline, diesel and olefin chemical raw materials) obtained by catalytic cracking of heavy oil, the removed carbon residues are burned in the regenerator to release heat. Part of the catalyst is heated as a heat source for cracking, and part of the heat is obtained by a heat collector to generate steam and sent out. Or power generation, the reaction temperature is as low as 500°C-650°C, and the requirements for heavy oil raw materials are relatively high, and the full and effective utilization of petroleum resources has not been achieved.

Abstract

The invention discloses a processing method for heavy oil. A gas-solid separating zone is formed in the upper part of a reactor, a thermal cracking zone is formed in the middle part, a gasifying zone is formed in the lower part, raw materials are led into the reactor from the bottom part of the gas-solid separating zone and are dispersed into oil drops through an atomizer, the light components in the oil drops are volatilized into oil gas in the process that the oil drops fall down in the thermal cracking zone, and the heavy components are condensed into tar. Therefore, the processing method has obvious social benefit and economic benefit.

Description

technical field [0001] The invention relates to a processing method of heavy oil. Background technique [0002] With the advancement of science and technology and the continuous development of economic construction, the problem of energy crisis has become the primary problem hindering the economic development and construction of various countries in the world. Affected by resources, the contradiction between supply and demand of crude oil in my country has become increasingly prominent. Since 1993, my country has become A net oil importer needs to spend a large amount of foreign exchange to import oil and oil products every year. [0003] Most of the crude oil in my country has a high content of residual oil and a low content of light oil. In addition, in recent years, the production of some heavy oil (heavy oil) has been increasing and the introduction of some foreign heavy crude oil has made the problem of lightening heavy oil more prominent. Heavy oil processing methods o...
