PURPOSE:To obtain a high active and inexpensive catalyst for hydrogenation by constituting the catalyst of ultrafine powder of base metal and its alloy manufactured by means of an evaporation method in gasses. CONSTITUTION:A catalyst for hydrogenation is constituted of ultrafine powder of about 100-500Angstrom grain size of base metal (for example, Fe, Co and Ni) or its alloy which is manufactured by heating and evaporation in inert gasses. Said catalyst may be ultrafine powder of base metal obtained by said method as it is and it is deposited on a carrier consisting of acidic and fire-resistant inorganic compounds. Said catalyst has activity which isn't inferior to conventional nobel metal catalyst when it is used for hydrogenation reaction and is inexpensive and easy in handling. Hydrogenated decomposition and hydrogenation of unsaturated bond or carbonyl group are incorporated for the hydrogenation reaction but the representative reaction among these is the hydrogenated decomposition of carbon-oxygen bond, carbon-sulfur bond, carbon-nitrogen bond, carbon-halogen bond or sulfur-sulfur bond. |
