【 摘 要 】

The development of new technological solutions in municipal solid waste management will reduce the adverse impact on the environment and human health. There are different methods of thermal disposal of municipal solid waste, such as incineration, pyrolysis,and gasification. The most effective and environmental method of thermal disposal is the gasification of solid wastes. This paper discusses the possibility of municipal solid waste gasification in underground coal gasification process and the prospects of gasification method following on from the analysis of the composition and properties of municipal solid waste. Municipal solid waste is a valuable carbonaceous feedstock that can be used in an underground coal gasification process to increase the life cycle of the underground gasifier, to produce additional volumes of synthesis gas, to stow the ash of municipal solid waste in mined-out space of underground gasifier. Operations of municipal solid waste preparation need to improve the efficiency of the gasification process. A considerable volume of municipal solid waste is an alternative carbonaceous resource, which can provide the needs of power and chemical industry for synthesis gas.
