    摘要： 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.

    摘要： A process for dimerizing olefins in the presence of a catalyst, a hydrocarbon feedstock containing C4 to C6 isoolefins is subjected to dimerization. The process comprises the steps of contacting the C4 to C6 isoolefins at conditions conducive to dimerization with a catalytic material comprising an acidic mesoporous molecular sieve, the catalytic material being thermally stable at a temperature of at least 900° C., and carrying out the contacting step essentially in the absence of butadiene and water in the feedstock. By means of the invention, the dimerization process can be operated over extended periods of time with prolonged maintenance intervals.
