Pulse flow reaction
A method of operating a multi-phase downflow reactor so as to induce a pulsing flow regime is disclosed. The pulse may be induced by increasing the gas rate while maintaining the liquid rate until a pressure drop sufficient to induce the pulse flow is achieved. The method is particularly useful in the sulfuric acid catalyzed alkylation of olefins in a reactor packed with a stainless steel/polypropylene mesh.
1. A method of operating a multi-phase downflow reactor comprising conditions of liquid and vapor flow to induce a pulse flow regime in a packing comprising a contact structure having a void space of greater than 50 volume %.
2. The method according to claim 1 wherein said void space is up to about 99 volume % open space.
3. The method according to claim 1 wherein said contact structure is comprised of inert material.
4. The method according to claim 1 wherein said contact structure is comprised of catalytic material.
