Abstract
A method of alkylating an alkylatable hydrocarbon with different alkylating agents, at different reaction temperatures and in a single reaction zone, in which an alkylatable hydrocarbon is contacted with an acid-type catalyst and at different points in an elongated reaction zone, the reaction zone effluent is separated into a hydrocarbon phase and a catalyst recycle phase and the reaction temperatures of the various alkylating agents are maintained at different temperatures by splitting the recycle catalyst phase into an equal number of streams and adjusting the reaction temperatures by adjusting the temperatures of the recycle catalyst phase streams, the relative proportions of the recycle catalyst phase streams or both. A method of starting-up the process and apparatus for conducting the process are also disclosed.
