Abstract
A process is disclosed for the concurrent production and hydrogenation of diisobutene in a single distillation column reactor containing both a dimerization catalyst and a hydrogenation catalyst by the dimerized of isobutene to diisobutene. The catalysts may be in alternating beds or physically mixed together in one or more beds. Alternatively a bifunctional catalyst having both dimerization and hydrogenation properties may be used.
Claims12
A process for producing C8 alkane comprising:
- (a) feeding isobutene and hydrogen to a distillation column reactor containing a dimerization catalyst and a hydrogenation catalyst;
- and
- (b) concurrently in said distillation column reactor:
- (i) contacting said isobutene with said dimerization catalyst under conditions to preferentially react a portion of said isobutene with itself to produce diisobutene,
- (ii) contacting said diisobutene with hydrogen in the presence of said hydrogenation catalyst to produce C8 alkane, and
- (iii) separating unreacted isobutene and diisobutene and C8 alkane by fractional distillation.
