Biomass gasification polygeneration technology can well address both the economic and environmental issues that impeded the development of biomass gasification technology. To further improve the utilization efficiency of biomass, preactivation of gasified carbon is realized in the gasification reactor. The aim of this study is to adopt a new gasification reactor and an environmental protection combustion chamber to obtain high value-added activated carbon with clean heating. In this paper, an experimental study on the fruit-wood waste gasification heating coproduction of an activated carbon system was carried out. The results show that the yield of gasified carbon is 20.22%, the specific surface area of gasified carbon reaches 590 m 2 /g, the yield of activated carbon is 10.37%, and the gas yield is 1.9 Nm 3 /kg. The gasification efficiency of the system is 57.83%, the energy that is transferred to the activated carbon is 18.72%, and the percentage of fixed carbon is 24.3%. Compared with the biomass particle, coal, and natural gas heating projects, the environmental protection benefits of the project are significant, and the negative emission of CO 2 is realized. Compared with the heating benefit of coal and natural gas, the economic benefit of this project is more significant.
