Abstract
A method of producing a high octane alkylate from ethylene and isobutane by reacting ethylene and isobutane under catalytic conversion conditions. The ethylene and isobutane are contacted with a first catalytic material comprising a dimerization catalyst (i.e, for dimerizing ethylene) and a second catalytic material comprising an alkylation catalyst. The first and second catalytic materials are separate and distinct from each other. A high octane alkylate is recovered as a result of reacting the ethylene and isobutane in the presence of the first and second catalytic materials.
Claims17
A method of producing a high octane alkylate from ethylene and isobutane, comprising:
- (a) reacting a feed comprising ethylene and isobutane, wherein ethylene is the only olefin contained in said feed, under catalytic conversion conditions, and wherein said ethylene and isobutane are contacted with (i) a first catalytic material comprising a dimerization catalyst and a material which promotes regeneration of said dimerization catalyst and (ii) a second catalytic material comprising an alkylation catalyst wherein said first catalytic material and said second catalytic material are separate and distinct from each other, and wherein said first catalytic material and said second catalytic material have been combined physically into particles or pellets whereby each of said particles or pellets contains said first catalytic material and said second catalytic material;
- and
- (b) recovering a high octane alkylate from step (a).
