摘　　要：本文对影响煤炭热解产物分布的因素进行了归纳总结,重点分析了煤质性质、热解条件、预处理、催化剂和共热解等因素对煤炭热解产物分布的影响.通过控制这些因素,可以提高煤炭转化效率,并调控热解反应产物分布.开发高效加氢催化剂、添加生物质等富氢物质进行共热解是提高煤热解焦油收率及调控产物分布的重要措施.The influence factors of product distribution of coal pyrolysis were summarized. It would indicate that properties of coal, pyrolysis conditions, pretreatment, catalyst, co - pyrolysis had a major impact on coal pyrolysis. By controlling these factors, the efficient of coal conversion was increased and the products distribution from coal pyrolysis was regulated. Development of efficient hydrogenation catalyst and co -pyrolysis with other hydrogen - rich material are important measure of improvement coal pyrolysis tar yield and regulation of product distribution.
