Abstract
Method of producing alkylates in which an isoparaffin, olefin, a diffusing agent and a solid, acid catalyst are combined to form a three phase reaction mixture; a hydrocarbon phase containing primarily isoparaffin, a diffusing agent phase containing the diffusing agent, olefin and diffuse isoparaffin and a solid, acid catalyst phase, the diffusing agent being a polar solvent in which the olefin and aromatics are soluble.
Claims20
A method of producing alkylates comprising:
- a) combining an isoparaffin and an olefin and a diffusing agent to form a reaction mixture having at least three phases, a hydrocarbon phase comprised primarily of the isoparaffin, a diffusing agent phase comprised of the diffusing agent, olefin and diffuse isoparaffin and a solid, acid catalyst phase, said diffusing agent comprising a polar solvent in which the olefin is soluble and in which the isoparaffin is soluble to the extent of from about 5 to 200 g/L;
- and
- b) reacting the mixture produced in step (a) in the presence of the solid, acid catalyst phase under conditions in which at least a portion of the isoparaffin reacts with at least a portion of the olefin to produce the alkylates.
