Effect of the Operation Conditions on Gasification of Municipal Solid Waste

Gasification of municipal solid waste (MSW) is one of the promising methods to offer new energy resources during wastes reduction. The gasification is via volatile stage, tar cracking and reforming, and carbon combustion stage of MSW. The efficiency, yield, and concentration of produced gases are varied due to parameters changing during gasification. This contribution is focused on optimization of operating condition for MSW gasification by series experiments under different dominating parameters, such as reaction temperature, residence time, and oxygen concentration. The instantaneous gas yield was decreasing when the heating rate increases, because the reaction time was not enough and part combustible can not be converted into gas. The instantaneous gas yield and gas concentration were very high oxygen dependence. The concentrations of CO and H₂ were increasing with decreasing the oxygen concentration.
