b) In "Coal Quality Evaluation Indicators and Technical Requirements for Coal Chemical Industry", a list of coal quality evaluation indicators for various coal chemical projects has been added (see table 1); c) Add "Quality requirements for raw coal for medium and low temperature pyrolysis" (see Table 2); d) Add "quality requirements for raw coal for coking" (see Table 3); e) Add "quality requirements for raw coal for fixed bed coal gasification" (see Table 4); f) Add "quality requirements for raw coal for fluidized bed coal gasification" (see Table 5); g) Add "quality requirements for raw coal for coal-water slurry entrained gasification" (see Table 6); h) Add “Quality requirements for raw coal for dry coal powder entrained flow bed coal gasification” (see Table 7); i) Add "quality requirements for raw coal for direct liquefaction" (see Table 8); j) Delete "resource requirements of coal for coal chemical industry" (see Chapter 5 of the:2009 edition): Please note that some content of this document may be patented: The issuing agency of this document assumes no responsibility for identifying patents: This document is proposed by China Coal Industry Association: This document is under the jurisdiction of the National Standardization Technical Committee of Coal Chemical Industry (SAC/TC469): This document is drafted by: Coal Science and Technology Research Institute Co:, Ltd:, National Energy Investment Group Co:, Ltd: Coal Management Branch Company, Lu'an Chemical Group Co:, Ltd:, Inner Mongolia Yitai Group Co:, Ltd:, Jinneng Holding Group Co:, Ltd:, Shaanxi Coal Chemical Industry Group Co:, Ltd: responsible company: The main drafters of this document: Ding Hua, Ma Junxiang, Qi Zhongli, Jiang Yu, Bai Xiangfei, Zhao Yanli, Ding Ding, Gao Yuan, Shi Yongsheng, Chang Xiaohua, Li Changlun, Chen Yafei, Yang Kesheng, Yang Yong: This document was first published in:2009 and this is the first revision:IntroductionThe coal chemical technology for producing solid products, liquid products and gas products using coal as raw material mainly includes: ---Coal low temperature pyrolysis, coking and downstream product processing; --- Coal direct hydroliquefaction; ---The production of oil products after coal gasification, etc:; ---Coal gasification to produce methanol and downstream products; ---Coal gasification to produce synthetic ammonia and downstream products: Different coal chemical technologies and projects have different requirements on coal resources and coal quality: This document is based on the current coal chemical technology in my country The status quo of coal requirements for technical use, formulated in combination with the status of coal resources and coal quality characteristics in my country, takes into account the coal quality requirements of various coal chemical technologies and processes: At the same time, the characteristics of coal resources were fully considered: The formulation of this document, on the one hand, can guide the selection of raw coal for specific coal chemical technologies, and On the other hand, for a specific coal resource, the appropriate coal chemical technology technology can be selected according to its coal quality characteristics, and the Promote comprehensive utilization of coal resources: This document starts from the matching requirements of coal chemical technology and project with coal resources and coal quality characteristics, regulates coal used in coal chemical industry, and proposes The specific coal quality indicators and technical requirements that need to be considered in various coal chemical technologies should be further protected under the premise of ensuring the quality of coal used in coal chemical industry: China's high-quality coal and scarce coal: The formulation of this document is a tool for the development and utilization of my country's coal resources and the healthy and orderly development of the coal chemical industry: have an important guiding role: Technical Guidelines for Coal Use in Coal Chemical Industry1 ScopeThis document specifies the quality evaluation indicators and control requirements of raw coal for coal chemical industry The guiding principles for the determination of coal resources with high harmful element content and the design of coal chemical projects: This document is applicable to coal chemical industry such as coal medium and low temperature pyrolysis, coal coking, coal gasification and direct coal liquefaction for new construction, reconstruction and expansion: project:2 Normative referencesThe contents of the following documents constitute essential provisions of this document through normative references in the text: Among them, dated citations documents, only the version corresponding to that date applies to this document;
