<P>PROBLEM TO BE SOLVED: To provide a solid catalyst suitable for manufacturing of bio-diesel oil from raw fat and oil, and a manufacturing method of the catalyst. <P>SOLUTION: The solid catalyst is calcium diglyceroxide obtained by reacting a raw material of calcium oxide with a specific basic strength and an amount of base, or calcium hydroxide obtained by hydrating the calcium oxide, with a methanol solution of glycerol in a heated circulating flow, or calcium methoxide obtained by reacting the raw material with methanol in a heated circulating flow, the calcium methoxide having a surface area of 40m<SP>2</SP>/g or more. The surface of a carrier of the catalyst is coated with calcium diglyceroxide or calcium methoxide. The carried type catalysts are obtained by fixation of calcium carbonate by a carbon dioxide combining method or impregnating and fixation of calcium acetate followed by firing. <P>COPYRIGHT: (C)2008,JPO&INPIT |
