Method for rapidly treating kitchen waste for co-production of high-value fuel gas and biochar

The invention discloses a method for rapidly treating kitchen waste for co-production of high-value fuel gas and biochar. The method comprises the steps that firstly, the kitchen waste is pre-treated;then water is supplemented until the water content reaches 80-90%; the kitchen waste is injected into a supercritical reactor by using a high-pressure pump, and heating is carried out until a supercritical state is reached; reaction is carried out in the reactor for 20-40 minutes; and finally the kitchen waste passes through a gas-water separator, a filter, a scrubber and a dryer so as to obtainthe high-value fuel gas and the biochar. The method has the advantages that the treatment speed is greatly increased, the treatment is more thorough, the occupied area is small, secondary pollution isavoided, the daily treatment capacity of the kitchen waste is greatly improved, and the practical problems that the yield of the kitchen waste in China is high and is increased year by year can be better solved. 本发明公开了种快速处理餐厨垃
