[Utilization strategies of Chinese medicinal solid waste by pyrolysis and gasification technology].

ABSTRACT

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.
