Abstract
The present invention provides a method and system for preparing fuel gas by utilizing an organic waste with high water content. The method comprises the following steps: 1) providing an organic waste with high water content; 2) performing hydrothermal reaction by using the organic waste with high water content as a reactant to obtain a hydrothermal reaction product; 3) enabling the hydrothermal reaction product to generate steam, and separating a solid product and an oily liquid product in the hydrothermal reaction product; 4) performing gasification reaction by using the solid product, the oily liquid product and the steam as reactants to obtain a gasification reaction product; and 5) purifying the gasification reaction product to obtain clean fuel gas. The present invention further provides a system for preparing fuel gas. The method can be used for preparing clean fuel gas from the organic waste with water content of 60% or more.
