Method by utilizing livestock manure to produce hydrogenous gas and other products in a step-by-step thermal decomposition way and device

The present invention discloses a method of manure Pyrolysis step a hydrogen-rich gas and other products, comprising the steps of: manure compost and after drying into biochar carbonized, milled to a powder RICH feedstock of the hydrogen gas into the fluidized bed reactor, while the steam generating means generates superheated steam into the reactor to the reaction feed in a fluidized state, and the water gas shift reaction to produce hydrogen rich gas at elevated temperatures. Hydrogen rich gas separated by the cyclone means, condensing means and filter purification means hydrogen entering subsequent processing stages, the present invention also discloses an apparatus for implementing the above method, the present invention discloses a method no wastewater emissions, no negative impact on the environment, while achieving the reduction and resource utilization of livestock wastes.
