NOVELTY - An apparatus for catalytic gasification of refined biomass fuel comprises a fuel hopper (10) to receive fuel and including a screw feeder (11); a catalytic circulating fluidized-bed gasifier (20) having a shutter, a hot air pipe (21) and stream (22) pipes; a dust collector (30) to collect fly ash; a catalytic reformer (40) including filter absorbent (41) and fluidized catalyzed (42) beds; a heat exchanger (50); a tar scrubber (60); and gas-holder (70).    USE - For low-temperature catalytic gasification of refined biomass fuel (claimed), for manufacturing gas fuel.    ADVANTAGE - The apparatus provides poison-resistance catalytic gasification of refined biomass fuel in first stage and increases gasification yield at a low temperature. The apparatus is compact and avoids need for a molten ash quenching system, in which calories of the produced gas are increased and ash formed not in molten state but as fly ash, by minimizing the content of carbon dioxide in the gas while decreasing the energy consumption of reaction system by decreasing the temperature of total process. The apparatus provides clean gasification of a selectively refined mixture (SOCA: Sludge-oil-coal-agglomerates) of biomass organic waste, heavy oil and coal. Since the temperature of a total gasification process is lower than a melting point of ash, powdery ash is generated and thus easily treated. Also, little heat is released due to the low process temperature, and therefore, a compact reactor may be designed to produce gas having a high caloric value. The generated tar is recovered and reused in other processes, and the gas fuel contains a small amount of ammonia. Thereby, oxygen consumption required to maintain the operation temperature is decreased, thus a desired fuel may be inexpensively produced. The gas product obtained by using a smaller amount of air has the same caloric value as a gas product resulting from conventional gasification using oxygen, therefore generating economic benefits. The apparatus pertains to clean energy producing techniques for converting a highly refined comprises sludge and coal into an inexpensive gas fuel having a high caloric value. The gasification is performed for a short time, hence achieving rapid gasification.    DETAILED DESCRIPTION - The duct collector is connected to the catalytic circulating fluidized-bed gasifier via a pipe extending from an upper portion of the catalytic circulating fluidized-bed gasifier to a sidewall of an upper portion of the dust collector. The catalyst reformer is connected to the dust collector via a pipe extending from the upper portion of the dust collector to a lower portion of the catalyst reformer, and including a lower layer of fixed filter adsorbent bed and an upper layer of fluidized catalyst.
