    摘要: The invention concerns a process for the alkylation of at least one isoaffin selected from the group formed by isobutane and isopentane by at least one olefin containing 2 to 6 carbon atoms per molecule in the presence of a liquid acid catalyst, the process comprising mixing a feed comprising the olefin to be converted with an effluent comprising a major portion of isoparaffin in a first mixing zone, and forming an emulsion of said catalyst in a hydrocarbon effluent comprising a major portion of isoparaffin in an emulsifying zone, said effluent constituting the continuous phase of the emulsion thus formed, then mixing a major portion of the emulsion of acid in hydrocarbon effluent with a major portion of the diluted feed comprising the olefin in a second mixing zone, followed by carrying out the majority of the reaction in a reaction zone which is supplied by the major portion of said mixture.
