NOVELTY - The apparatus (150) has contact unit (160) that dissolves the precursor of a catalyst or catalyst in a water soluble solvent, and contacts catalyst solvent and a water-containing solid raw material. A solid-liquid separation unit (170) separates the liquid mixture of the water-soluble solvent and water by contacting catalyst solvent and the water containing solid raw material from the solid raw material, such that precursor of the catalyst or the catalyst is supported.    USE - Apparatus for manufacturing solid raw material such as coal, biomass and tire chip. Can also be used in electric power generation system, manufacture of hydrogen, manufacture of synthetic fuel such as synthetic petroleum, and manufacture of chemicals such as urea.    ADVANTAGE - The gasification efficiency can be improved while removing water from water containing solid raw material such as peat, lignite, wood coal, subbituminous coal, biomass, and waste material. The production of nitrogen oxide can be reduced by making solid raw material to support an iron compound as catalyst or precursor. The cost required for water-soluble solvent can be reduced.    DETAILED DESCRIPTION - The reproducing unit (180) which reproduces the water soluble solvent from the liquid mixture. A return unit (190) returns the reproduced water-soluble solvent to the contact unit. The water-containing solid raw materials are coal and biomass selected from the group of waste material. The precursor of the catalyst is selected from the group of calcium compound, a potassium compound, and an iron compound. The water-soluble solvent is selected from the group of methanol, ethanol, a propanol, and acetone. INDEPENDENT CLAIMS are included for the following:    (1) solid raw material manufacturing method; and    (2) gasifying gas production method involves introducing the solid raw material by which the precursor of the catalyst is supported into the gasifier with flow medium forming the fluidized-bed.
