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.

Claim (Index 17):
The method according to  claim 1 , wherein the temperature of the gasification reaction is 700-800\u00b0 C., which is maintained by burning the clean fuel gas, wherein the burning amount L gas  of the clean fuel gas is calculated according to the following formula:\n HHV\u00d7L gas =C p,M \u222bm M dT+C p,ash \u222bm ash dT+C p,v \u222bm v dT+Q p +M\u00d7 2500 \n wherein HHV is heating value of clean fuel gas, in unit of kJ/Nm 3 ; L gas  is in unit of Nm 3 /kg material; m M  is content of dry material, in unit of %; m ash  is content of gasification residue, in unit of %; m v  is total gas output, in unit of Nm 3 /kg, wherein tar is also included if tar exists; Q p  is total reaction heat and is total heat effect of gasification reaction and enthalpy value for maintaining flue gas component produced during burning at gasification temperature, in unit of kJ/kg; M is residual water content of material after drying, in unit of %, m M +M=100%; C p,M , C p,ash , C p,v  are respectively specific heat of dry material, residue and produced gas, respectively in units of kJ/kg\u00b7\u00b0 C., kJ/kg\u00b7\u00b0 C. and kJ/Nm 3 \u00b7\u00b0 C.
