Abstract
A process for producing alkylated hydrocarbons includes the steps of: (a) combining a first feed stream comprising an olefin and an isoparaffin with an alkylation catalyst stream in a first alkylation reactor, (b) removing heat of reaction from the first alkylation reactor, (c) passing an effluent of the first alkylation reactor to a first reaction zone of a second alkylation reactor operating adiabatically to thereby form a first reaction zone effluent, (d) passing the first reaction zone effluent to a second reaction zone of the second alkylation reactor for mixture with a second feed stream comprising an olefin and an isoparaffin, and (e) passing an effluent of the second alkylation reactor to a settler for separation into a hydrocarbon stream and an alkylation catalyst effluent stream. An alkylation unit for carrying out the process is also disclosed.
