METHOD AND SYSTEM FOR PREPARING FUEL GAS BY UTILIZING ORGANIC WASTE WITH HIGH WATER CONTENT

WIPO Patent Application WO/2018/018615

A1

Provided are a method and a system for preparing a fuel gas by utilizing organic waste with a high water content. The method comprises the following steps: 1) providing organic waste with a high water content; 2) using the organic waste with a high water content as a reactant to perform a hydrothermal reaction, so as to obtain a hydrothermal reaction product; 3) making the hydrothermal reaction product generate steam, and separating a solid product and an oily liquid product from the hydrothermal reaction product; 4) using the solid product, the oily liquid product and the steam as reactants to perform a gasification reaction, so as to obtain a gasification reaction product; and 5) purifying the gasification reaction product, so as to obtain a clean fuel gas. Also provided is a system for preparing a fuel gas. A clean fuel gas can be prepared from organic waste with a water content of 60% or more by means of the method.
