Description

A kind of method using mixed refining technique processing oil and coal
Technical field
The present invention relates to a kind of method using mixed refining technique processing oil and coal, belong to petrochemical industry and coal chemical industry Field.
Background technology
In recent years, world petroleum resource worsening shortages, and the heaviness of petroleum resources and in poor quality problem are more and more brighter It is aobvious, but as the rapid growth of economy, society are growing day by day to the demand of oil product.Heavy Oil Processing Technology can not only have Effect utilizes petroleum resources, and can improve the economic benefit of oil-processing enterprises, still, the decompression residuum of oil plant processing at present (particularly content of beary metal is high) generally uses delay coking process, and its light oil yield is no more than 60%, and nothing during decoking Tissue dust emission can cause serious environmental pollution.
Based on the few fundamental realities of the country of China's coal heavy wool, coal liquifaction (coal chemical industry) item that many enterprises carried out successively in recent years Mesh, all using coal, first gas processed, gas synthesize the technique of oil product (industrial chemicals) again substantially, due to project investment is huge, operation not Stable, water consumption is more and the reason slower development such as carbon emission amount height.
Claim:
In order to solve the above problems, the present invention provides a kind of method using mixed refining technique processing oil and coal.
A kind of method using mixed refining technique processing oil and coal, three kinds of situations are divided into according to raw material difference:
