The skeletal metal catalyst for hydrogenation in fixed bed is prepared with the alloy powder of Al and one or several of Ni, Co, Cu and Fe as main material, jelly prepared with pseudothin diasphore and other inorganic matter as adhesive and sesbania powder, carboxymethyl cellulose or other natural or synthetic organic matter as pore template agent, and through direct kneading, formation, roasting and activation with caustic soda solution. The catalyst may be used in hydrogenating saturation of aldehyde, ketone, nitrile and other unsaturated compound in fixed bed, and has excellent activity, selectivity and stability.
