Abstract
A coal gasification process is provided based on the grading conversion of carbon hydrogen components of coal, wherein the coal gasification process comprises a carbonization process, a carbon monoxide-producing process and a shift reaction process. By blending the coke-oven gas, carbon monoxide and hydrogen produced in the above processes in different ratios, coal gasification syngases with various carbon hydrogen ratios can be obtained. Further, the coal gasification process does not need pure oxygen to take part in the reactions, and has several advantages, such as high gasification efficiency, low equipment investment costs, less limitation on the types of coal and flexible adjustment of the gasification products.
