Abstract
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.
Claims10
A method of producing alkylate in a sulfuric acid alkylation comprising feeding a hydrocarbon component consisting of an olefin, olefin precursor or mixture thereof and an isoalkane, in at least a partial gaseous state to a downflow reactor in the presence of liquid sulfuric acid fed at a constant rate and an internal static mixing system wherein the rate of feed of said olefin, olefin precursor or mixture is increased until a pressure drop sufficient to induce the pulse flow is achieved.
