    摘要: The selective dimerization of isoolefins, such as isobutene or isopentane, or mixtures thereof, may be conducted in a system including a series of fixed bed reactors and a catalytic distillation reactor. The system may provide for conveyance of the fixed bed reactor effluents, without componential separation, to a downstream reactor. It has been found that a high selectivity to the dimer may be achieved even though intermediate separation of the desired product from unreacted components between reactors is not performed. Further, embodiments provide for use of a divided wall column for recovery of a high purity dimer product, reducing unit piece count and plot size.

    摘要: An oligomerization catalyst for olefins having from 2 to 6 carbon atoms is produced by treating aluminum oxide with a nickel compound and a sulfur compound, either simultaneously or firstly with the nickel compound an then with the sulfur compound, and subsequently drying and calcining the resulting catalyst, wherein a molar ratio of sulfur to nickel in the finished catalyst of from 0.25:1 to 0.38:1 is set in this way. The catalyst and its use are also described.
