PROCESS FOR OLIGOMERIZING OLEFINS
A process for oligomerizing olefinic, lower hydrocarbons. The process comprises the steps of feeding a fresh olefinic hydrocarbon feedstock to a reaction zone; contacting the olefinic hydrocarbons of the feedstock with an acidic catalyst in the reaction zone in order to dimerize at least a part of t...

| description | A process for oligomerizing olefinic, lower hydrocarbons. The process comprises the steps of feeding a fresh olefinic hydrocarbon feedstock to a reaction zone; contacting the olefinic hydrocarbons of the feedstock with an acidic catalyst in the reaction zone in order to dimerize at least a part of the olefinic hydrocarbons, withdrawing an effluent containing oligomerized olefins from the reaction zone; and conducting the effluent to a separation zone, wherein the oligomerization reaction product is separated from said effluent. According to the invention, the reaction is carried out in homogeneous phase comprising a solvent for olefinic hydro-carbons, maintained at supercritical conditions. By using supercritical carbon dioxide as a solvent deactivation rate of catalyst can be diminshed. Carbon dioxide is easy to remove from the product mixture and spent reaction medium can be used for regeneration of the catalyst. |
