Title:
METHOD FOR PREPARING GASIFICATION COKE FROM WASTE CIRCUIT BOARD RESIN POWDER PYROLYSIS COKE
Document Type and Number:
WIPO Patent Application WO/2022/089667
Kind Code:
A1
Abstract:
A method for preparing gasification coke from waste circuit board resin powder pyrolysis slag coke. The main steps are as follows: quantity proportioning, cold press molding, enhanced oxidation and stepped heating carbonization. According to the invention, the coke in a waste circuit board resin powder pyrolysis slag is used to partially replace refined coal powder to obtain a high-calorific-value gasified coke and achieves high-value utilization of waste resources. The method is characterized by a simple and easy process, low manufacturing costs and broad adaptability, and is beneficial for increasing the economic benefits and social benefits of enterprise production.
