    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: Process for producing gasoline components. The process comprises feeding a fresh olefinic hydrocarbon feedstock to a reaction zone, in which its structure is first isomerized. The isomerized hydrocarbon is drawn out of the first reaction zone and conducted to a second reaction zone, where the isomerized hydrocarbon is dimerized. The dimerized reaction product is drawn out of the second reaction zone and separated from the flow in a separation zone. Because there are more isoolefins present in the dimerization unit feed, more isoolefin dimers useful as fuel components can be produced.
