有机固废共热解气化产物及其污染物排放特性研究综述

Review of research on co-pyrolysis gasification products and pollutant emissions of organic solid wastes

综述了国内外热解气化技术现状以及其遇到的问题,总结了热解气化技术特点,归纳了国内外共热解气化的研究现状;探讨了共热解的优缺点、生物质与有机工业固废、餐厨垃圾的共热解机理及其协同效应,以及在共热解过程中生物量、混合比和热解温度对共热解产物的影响。结果表明,生物质与有机固废共热解相比于单种生物质热解可以提高能源资源的利用率,并降低多种污染物的排放水平。但当前对热解气化特性差异较大的混合组分的反应机理研究仍不充分,对催化热解气化过程中催化剂的选取原则也有待深入研究。

The present technological situation of pyrolysis and gasification in domestic and abroad applications and their encountered problems were reviewed.The technological features and recent research situation of pyrolysis and gasification were systematically summarized.The advantages and disadvantages of co-pyrolysis,the co-pyrolysis mechanism and synergistic effect of biomass and organic solid waste,kitchen waste,and the effects of biomass,mixing ratio and pyrolysis temperature on Co-pyrolysis products were also discussed.Results show that co-pyrolysis of biomass pyrolysis and organic solid wastes can improve the utilization rate of energy resources and reduce the emissions of many pollutants compared with single biomass pyrolysis.However,the research on reaction mechanism of mixtures with different pyrolysis and gasification characteristics is still insufficient,and the selection principle of catalysts in the process of catalytic pyrolysis and gasification needs to be further studied.
