METHOD OF PRODUCING THE NICKEL CATALYST FOR UNSATURATED AND AROMATIC HYDROCARBONS HYDROGENATION Russian patent published in 1997 - IPC

Abstract RU 2080178 C1

FIELD: petroleum chemistry and oil processing. SUBSTANCE: invention relates to catalytic hydrogenation of benzyl cyanide. Developed method of nickel catalyst preparing for hydrogenation of unsaturated and aromatic hydrocarbons involves chemical reduction from alkaline solution at pH = 13-14 containing nickel chloride and hydrazine hydrate at the following ratio of components, g/l: nickel chloride 25-100, and hydrazine hydrate 125-500. Process is carried out at the room temperature for 10-20 min and the obtained powder is washed out by decantation and dried. EFFECT: improved method of catalyst making. 2 cl
