Porous carbon material produced from gasified coal slag, production method and application of porous carbon material produced from gasified coal slag

The invention relates to a porous carbon material produced from gasified coal slag, a production method and application of the porous carbon material produced from the gasified coal slag, and belongsto the field of high-added-value resource utilization of solid waste resources of the coal chemical industry. According to the method for producing the porous carbon material from the gasified coal slag, by means of the characteristics that a refined carbon material recovered from the gasified coal slag has well-developed pores and a large specific surface area, through acid pickling for de-ashingand carbonization, the porous carbon material with a specific surface area and pore volume larger than those of the refined carbon material is obtained. The porous carbon material is large in specific surface area, few in impurity and low in cost, and has high market competitiveness. According to application of the porous carbon material as an electrode material, electrochemical tests indicate that test results are superi
