摘要： In a conventional reactor into which at one end portion there are fed olefin, isoparaffin and HF acid, or other catalysts, and from which an alkylate containing product is passed to a phase separator or settling zone, there is added to the reactor to a downstream portion therein, beyond the original point of entry of the first olefin feed a second portion of olefin feed together with hydrocarbon phase recycled from the phase separator or settling zone.

摘要： 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.

摘要： A continuous process for the alkylation of an alkylatable hydrocarbon with an alkylating agent in the presence of an acid-type catalyst, including; contacting an alkylatable hydrocarbon with an alkylating agent in the presence of an acid-type catalyst at a temperature and pressure and for a time sufficient to alkylate the alkylatable hydrocarbon; separating the reaction effluent stream into an alkylate product phase and a catalyst phase containing catalyst-soluble oil; cooling the catalyst phase to a temperature essentially equal to the alkylation reaction temperature; recycling the cooled catalyst phase to the alkylation reaction; contacting a diolefinic hydrocarbon with an acid-type catalyst at a temperature and pressure sufficient to form additional catalyst-soluble oil and combining the additional catalyst-soluble oil with the circulating catalyst phase. In accordance with another aspect of the invention, a quantity selected from the amount of catalyst-soluble oil, water and/or the total of the amount of catalyst-soluble oil and water in the catalyst phase is controlled, within specific limits. A start-up procedure and apparatus for carrying out the process are also included.

摘要： A stream containing styrene and mixed xylenes, such as may be recovered from pyrolysis gasoline, is fractionated to obtain a stream containing ortho-xylene and styrene. Styrene is separated from the latter stream by an extraction process which employs succinonitrile as the solvent. Styrene is selectively absorbed by the succinonitrile, and is subsequently recovered from the resulting extract phase.
