摘要：

alpha-Methylstyrene hydrogenation in a fixed catalyst bed is studied experimentally and theoretically for a cocurrent downflow of the gas and liquid. Gas-phase hydrogenation on dry catalyst granules disturbs the liquid-vapor phase equilibrium. A dimensionless parameter related to the Raoult-Dalton law fora liquid-vapor mixture is suggested to characterize phase disequilibrium in the system.
