Abstract

The invention relates to a method for producing synthesis gas by catalytically reforming coal, natural gas and carbon dioxide. The method comprises the steps of preparing the synthesis gas and catalytically reforming a fluidized bed. The synthesis gas is obtained by catalytically reforming the coal, the natural gas and the CO2 fluidized bed, the ratio of H2 to CO is about 1, and the synthesis gas can be directly used as a raw material of oxo synthesis and F-T (Fischer-Tropsch) synthesis oil. The method has the advantages of energy conservation and emission reduction and environment improvement, meets the circular economy policy implemented by the country, and further meets the national requirement for establishing resource-saving and environment-friendly chemical enterprise.

Description

【Technical Field】 [0001] The invention belongs to the technical field of coal chemical industry. More specifically, the present invention relates to a method for producing synthesis gas from the catalytic reforming of coal, natural gas and carbon dioxide. 【Background technique】 [0002] Coal resources are the most reserves of fossil resources, and they are also the most exploited, used, and used resource. Among the many ways to transform coal resources, gasification is the best way to achieve clean and efficient use of resources. Coal gasification has developed rapidly in recent years, especially the large-scale, high-temperature, high-pressure wet gasification technology is widely used in the fields of synthetic ammonia and methanol. Due to the inherent properties of coal and the process characteristics of wet gasification, the coal gasification temperature is very high. The high-temperature synthesis gas is generally cooled by chilling, and its sensible heat is not recovered ...
