With the advantages of extensive sources, easy collection, renewability, high yield, carbon circulation, low pollution, and so on, Chinese medicinal solid waste can be converted into clean gas by pyrolysis and gasification, which is then able to serve for industrial production. This is of great practical significance in the context of energy shortage and for solid waste recycling in China. This paper reviews the research progress on biomass gasification principle, gasification medium, and reactor in gasification technology of Chinese medicinal solid waste in recent years. Meanwhile, based on the summary of related research, the defects and improvement measures regarding raw materials, gasification agents, by-products, and reactors were discussed, which provides direction for further development in the gasification technology of Chinese medicinal solid waste in the future.
中药固体废弃物具有来源广泛、易于收集、可再生、产量高、碳循环、污染低等优点,通过热解和气化可转化为清洁气体,进而用于工业生产。这在能源短缺背景下以及我国固体废弃物回收利用方面具有重大现实意义。本文综述了近年来中药固体废弃物气化技术中生物质气化原理、气化介质和反应器的研究进展。同时,在相关研究总结的基础上,探讨了原料、气化剂、副产物和反应器方面存在的缺陷及改进措施,为未来中药固体废弃物气化技术的进一步发展提供了方向。
