Abstract
The kinetics of the catalytic hydrogenation of acetone on nickel fine particles supported on active carbon particle was studied by a differential type of flow reactor.Initial rates of reaction without 2-propanol were measured at atmospheric pressure over the following range of conditions : Temperature, 125210 [°C]; Partial pressure, Pa=720 [kPa], Ph=750 [kPa]. AS a result, the most feasible rate-controlling step was found to be in the surface reaction between one adsorbed acetone molecule and one adsorbed hydrogen molecule on the same type of active sites. The final equation recommended for the vapor-phase hydrogenation of acetone on a nickel catalyst is r=kKaKhPaPh/ (1+Ka+Pa-KhPh)2
