Gasification Characteristics of Combustible Solid Waste with Additives and Kinetics Study

The effects of additives for combustible solid waste gasification were determined by using a thermogravimetric analysis/differential scanning calorimetry analyzer, and kinetics parameters of gasification reaction are evaluated. Results showed that the mass loss and the mass loss rate of sawdust gasification could be increased by adding plastics, and sawdust gasification starts in advance after adding sodium chloride (NaCl). The reaction rate and the activation energy of gasification reaction could be increased by NaCl and plastics slightly. While the mass loss and mass loss rate of paper gasification could be decreased by adding potassium carbonate (K 2 CO 3 ) and those are increased by adding sodium dodecyl benzene sulfonate (LAS). The activation energy of gasification reaction could be reduced by K 2 CO 3 and LAS.
