NOVELTY - Water content of livestock manure is reduced and the dried raw materials are sent to carbonizing furnaces, to obtain biocarbon and fuel gas. Biocarbon is ground and sent to a fluidized bed reactor. Superheated steam is supplied to the reactor and water gas reaction is carried out, to generate low-molecular gases. Gas is separated from solid by passing the gas from the reactor through a cyclone separator, then gas is separated from liquid by a condenser, and finally the substance is filtered using a membrane filter.    USE - Production of hydrogen-rich gas and other products e.g. compost, biocarbon, and gas with low thermal value by fractional pyrolysis of livestock manure (all claimed).    ADVANTAGE - The method generates no wastewater and waste gas, is environmental-friendly, and enables livestock resource utilization.    DETAILED DESCRIPTION - Water content of livestock manure is reduced by composting such that the water content of raw materials in the carbonization stage is as low as 20% or less. The dried raw materials are sent to carbonizing furnaces of stages (I,II) for reaction, to obtain biocarbon and fuel gas with low fuel value. Biocarbon is ground into powder and sent to a fluidized bed reactor. Superheated steam generated by a steam generator is supplied to the fluidized bed reactor and water gas reaction is carried out with biocarbon in the presence of an alkaline-metal catalyst at high temperature, to generate low-molecular gases such as hydrogen and carbon monoxide. Gas is separated from solid by passing the gas from the reactor through a cyclone separator, then gas is separated from liquid by a condenser, and finally the substance is filtered using a membrane filter. An INDEPENDENT CLAIM is included for device used for production of hydrogen-rich gas/other products by fractional pyrolysis of livestock manure, consisting of carbonizing furnace (1), carbonizing furnace (2), and a grinder. The outlet of a material cabin (4) is connected with a spiral feeding device (5). A material outlet of the spiral feeding device is connected with a reactor (8). A steam outlet of a steam generator (7) is connected with a cyclone separator (9). The reactor is provided with a probe hole which is connected with a controller (6). A gas outlet of the cyclone separator is connected with the inlet of a condenser (10). The gas outlet of the condenser is connected with the gas inlet of a filter (11).
