Background
Conventionally, in order to effectively utilize biomass resources including wastes such as plants, livestock products, fishery products, or wastes thereof, or wastes such as food wastes and livestock excrements, methane (CH 4) gas is generated from biomass resources by a methane fermentation apparatus. Further, if necessary, the methane gas generated is converted into hydrogen gas by pyrolyzing the methane gas through a gas reformer.
However, when methane gas is converted into hydrogen, a heat source for thermal decomposition is required. And as such a heat source, an external heat source or fuel is generally used, which leads to an increase in processing cost.

Another object is to provide a gas reformer which thermally decomposes remaining methane gas using heat energy generated from a combustion device to generate and recover hydrogen gas.
In the treatment method of the present invention, biomass resources containing sewage, such as plants, livestock products, fishery products or wastes thereof, or other wastes, such as wastes of livestock products and feces, are heated at 35 to 60 ℃, and the digestive juice and methane gas are removed.
The treatment method includes a heat exchange step of generating high-temperature superheated steam using heat energy generated in a combustion step between a combustion step and a gas reforming step, the gas reforming step including: preferably, the remaining methane gas generated in the methane fermentation process is pyrolyzed using heat energy of the high-temperature superheated steam generated in the heat exchange process to generate and recover hydrogen gas.
In addition, the liquid generated in the methane fermentation process is heated at the temperature of 320-400 ℃, and further comprises a carbonization process, wherein the carbonization process generates carbonized materials, and the carbonized materials generated in the carbonization process are more suitable to be used as combustion fuel in the combustion process.

Referring to fig. 1, an embodiment of the present invention is provided, and fig. 1 is a flow chart of a system and a method for pyrolysis of biomass resources for comprehensive utilization, wherein a processing system 1 of biomass resources of the present invention is mainly composed of a methane fermentation device 2, a combustion device 3 and a gas reforming device 4, and the methane fermentation device 2 heats biomass resources (including plants, livestock products, fishery products or waste thereof, or food waste, livestock product manure and other waste) at a temperature of 35-60 ℃ to generate a digestive liquid and methane gas. The combustion device 3 is a device that generates heat energy by combusting a part of the methane gas generated by the methane fermentation device 2 with an oxygen-containing gas. The gas reforming device 4 is a device that generates and recovers hydrogen gas by thermally decomposing the remaining methane gas generated by the methane fermentation device 2 using the heat energy generated by the combustion device 3.
As shown in fig. 1, a biomass resource is input to a methane fermentation apparatus 2 through a receiving tank 5, and then the biomass resource is heated at 35 to 60 ℃ to produce a digestion liquid and methane gas (methane fermentation). Procedure). This is because if the temperature is below 35 ℃, the methane bacteria will be inactive, and if the temperature exceeds 60 ℃, the methane bacteria will be killed. Further, in order to produce | methane gas generation more efficiently, it is most appropriate to heat the biomass resource in a medium temperature methanogen activity temperature range of 35 to 37 degrees centigrade or a high temperature methanogen activity temperature range of 55 to 60 degrees centigrade.
