摘要： The invention relates to a process for dimerizing lower, olefinic hydrocarbons. In particular, the present invention concerns a process for dimerizing C3–, C4 and C5-olefins with a medium pore zeolite under process conditions allowing selective dimerization According to the invention, fresh olefinic hydrocarbon feedstock is fed to a reaction system including at least one reaction zone and at least one separation zone. The olefinic hydrocarbon feedstock is contacted with an acid catalyst at conditions in which at least a part of the olefins dimerizes. The effluent from the reaction zone is conducted to the separation zone where dimerized reaction product is separated from said effluent.

摘要： The invention relates to a method for dimerizing isobutene, wherein, in dimerizing conditions, the isobutene is brought into contact with a porous cation exchange resin comprising a styrene polymer, which is cross-linked with divinyl benzene, and any sulphonic acid groups adhering to the polymer. The harmful deactivation of this catalyst, which is caused by the accumulation of the oligomers and polymers of isobutene and other C4-olefins in the cation exchange resin catalyst, is essentially decreased by selecting the cation exchange resin from a group including cation exchange resins, the acid capacity of which is 4.7 equivalents/kg at a minimum, and the portion of divinyl benzene units of which is 5% by weight at a minimum and smaller than 20% by weight.
