Abstract: |
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. |
Key words: coal pyrolysis influence factor coal tar |
