Experimental studies on municipal solid waste pyrolysis in a laboratory-scale rotary kiln

A laboratory-scale, externally heated, rotary-kiln pyrolyser was designed and built. Pyrolysis tests were performed. Solid wastes (paper, paperboard, waste plastics including PVC and PE, rubber, vegetal materials, wood, and orange husk) were tested. The effects of heating methods, moisture contents and size of waste on pyrolysis gas yields and compositions, as well as heating values, were evaluated.
