The Pyrolysis Characteristics of Four Kinds of Agri-Forestry Biomass Waste

Using TGA to study bagasse, peanut shell, rice husk, pine sawdust and other four kinds of agricultural and forestry wastes, and establish the apparent dynamics model of biomass Pyrolysis. Experimental research proved: the DTG curve of bagasse differs from the other three kinds of biomass. It shows two distinct peaks form. For bagasse, because of its dual weight-loss peak, its dynamics model reaction order in the lower temperature section is 2.5 and is 1.5 in the high temperature section. The dynamics model reaction order of the other three kinds of biomass is 2.5.
