Gasifying Kinetics Analysis on Mixing Municipal Solid Waste and Sludge

Abstract:

To gasify the mixture of sludge coming from urban sewage treatment residual and MSW is an ideal way to control the combustion of dioxins and other substances which pollute the atmosphere. Due to the complex composition of MSW and changing rapidly in the gasification parameters as much as possible, engineering require main ingredients and calorific value. The main ingredients of typical municipal sewage sludge and MSW are measured on thermobalance pyrolysis. The kinetics parameters of the gasification reaction are obtained, such as the activation energy and pre-exponential factor. These parameters synthesis mixture parameters provide the basis for hybrid gasification of the actual sludge and MSW reactor design, construction and operation.
