Combustible gas production during catalytic pyrolysis of municipal solid waste

Catalytic pyrolysis tests of municipal solid waste were carried out in a fixed bed reactor to produce combustible gases in this study. The influence of additives including CaCO3 and SiO2 with various amounts on the combustible gas productions was studied. The result shows that the catalytic effect of CaCO3 is better than that of SiO2. In addition, the pyrolysis of municipal solid waste was tested with the addition of CaO which was the thermal decomposition product of CaCO3. The catalysis of CaO mainly manifested in two aspects: catalyst CaO promoted the evolution of secondary cracking reaction and the reduction reaction between CO2 and C.
