Thread Content

The “General Guidelines for Determining Design Coal Types and Verification Coal Types for Modern Coal Chemical Industry Projects” (hereinafter referred to as the “Guidelines”), drafted under the leadership of the Coal Research Institute of China National Coal Group, was officially implemented on July 1. As the most important fundamental standard in the field of modern coal chemical industry, these General Principles provide a basis for determining the coal types to be used in the design of modern coal chemical projects as well as for verifying such choices. They enable precise improvement in the compatibility between the quality of raw coal and the production systems, and hold milestone significance for the preliminary decision-making and subsequent stable and efficient operation of coal chemical enterprise projects in the context of the \"dual carbon\" goals.
