Description

technical field [0001] The invention belongs to the technical field of coal gasification, and in particular relates to a production device and a production method for resource utilization of coal gasification waste residue. Background technique [0002] Under the background of "carbon neutrality" and "carbon peaking", every coal consumption index is very precious. Coal saving, energy saving and emission reduction are the general trend of the development of coal chemical industry in the future. Under the general background of the times, most coal chemical enterprises still have the phenomenon of coal loss and coal waste. Coal chemical enterprises use coal as raw material or adopt coal-water slurry process or pulverized coal process to obtain carbon monoxide, hydrogen, carbon dioxide and other process gases. While producing the process gas, the gasification reactor (gasifier) ​​discharges a large amount of waste residue, which also contains 10-45% carbon residue. The above-me...
