Abstract: Pyrolysis and gasification process of municipal solid waste was briefly clarified in this paper starting with various ways of municipal solid waste thermal conversion. The advantages and drawbacks of pyrolysis and gasification reactors were discussed. The research progress in municipal solid waste pyrolysis and gasification and the pilot test of pyrolysis and gasification technology together with their application status were all introduced. The effects of pyrolysis temperature and heating process on the yields and distribution of pyrolysis products，the effects of gasification temperature and oxygen equivalence ratio （RO） on the oxygen gasification reaction and the effects of gasification temperature，water vapor and the municipal solid waste mass ratio （S/M） on the steam gasification reaction were all illustrated clearly by comparing various experimental studies. It was found that the research on municipal solid waste pyrolysis and gasification focused on optimizing control parameters，improving reaction rate，promoting high-value target product and inhibiting the formation of other products and contaminants. Finally the research direction of municipal solid waste pyrolysis and gasification technology in the future was propsed that current research on municipal solid waste pyrolysis and gasification involved few research on the migration of pollutants during pyrolysis and gasification process and lagging study of the mechanisms of pyrolysis and gasification.
