Catalytic reactors

Abstract From the Canadian patent

A compact catalytic reactor defines a multiplicity of first and second flow channels arranged alternately in the reactor for carrying first and second , fluids respectively, wherein at least the first fluids undergo a chemical reaction. Each first flow channel containing a removable gas-permeable catalyst structure (20) incorporating a metal substrate the catalyst , structure defining flow paths therethrough with catalytic material on at , least some surfaces of each such path. The catalyst structure also incorporates a multiplicity of projecting resilient lugs (22) which support the catalyst structure (20) spaced away from at least one adjacent wall of the channel (17).
