    Abstract: PROBLEM TO BE SOLVED: To improve the storability and handleability of fatty acids by catalytically hydrogenating only carbon-carbon double bonds in the fatty acids and fatty acid derivatives by using a colloid of noble metal as a catalyst without using solvent. SOLUTION: Fatty acids and/or fatty acid derivatives are catalytically hydrogenated selectively under a hydrogen pressure up to 800 bar at maximum by using a catalyst that is a colloid of a single metal, binary or multiple metals selected from the group VIII or IB in the periodic table and is stabilized with a surfactant, for example, an amphoteric betain, or a solution catalyst prepared by dissolving the above-stated catalyst (the homogeneous catalyst) or, a heterogeneous catalyst, that are prepared by using previously formed single, binary or multi-metal colloid and their solutions and depositing them on a carrier. In a preferred embodiment, a bulk type carrier-supported catalyst is used to effect the catalytic hydrogenation reactions in a fixed bed reactor or in a tubular reactor.
