Abstract: Designed coal quality is an important design basis of modern coal chemical project, which could affect the stable operation of the project directly.In this text, based on the experience in the construction of Shenhua coal chemical projects, the program to determine designed coal quality was proposed.Modern coal gasification technology commonly used in coal chemical industries include:dry feed entrained flow gasification technology, coal-water slurry gasification technology, fixed bed gasification technology and fluidized bed gasification technology.The coal quality analysis projects were generalized based on different coal gasification technology for different coal quality requirement.In the coal sample collection and analysis process, acquisition of coal sample representative is prerequisite to typical coal quality data obtained.In this paper, according to the stage of coal mine, the different coal sample acquisition scheme were proposed, including sampling sites, the types of coal sample, sample weight, sample size and sampling mode.Besides, the coal sample preparation, analysis and the final data checking work also discussed in this paper.

Key words: coal chemicals industry, designed coal quality, coal gasification
