Trickle Column Reactors

Trickle column reactors combine the advantages of continuous operation at high catalyst efficiency, inherent in gas-phase processes, with the advantages of working under mild conditions, inherent in liquid-phase processes. However, considerable attention has to be given to the design of catalysts for use in such reactors. Studies conducted in the Johnson Matthey Research Laboratories have led to substantial improvements over past practice and several processes of potential industrial interest have been developed.
