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.
