Database of physical and chemical properties for solid wastes were constructed through investigation for single typical component and their mixture of solid wastes. The particulate trajectory model and heat transfer model were developed, based on the studies of Characteristics of solid wastes movement and heat mass transfer in rotary kiln. Pyrolysis experiments of solid wastes in lab and pilot scale rotary kiln pyrolyzers were performed. Mechanism of pyrolysis for typical solid wastes was analyzed. The characteristics of pyrolytic products, such as physical and chemical properties, composition and combustibility, etc, were investigated. A neural network model for the prediction of yields and properties of pyrolysis products was developed. Then, the potential applications of pyrolytic products and the substitution of pyrolytic fuels for corresponding commercial furls were investigated. The optimization of energy recovery and utilization for different wastes through pyrolysis was analyzed.
