摘要： An improved reactor for the autorefrigerant alkylation process has a generally cylindrical upright reactor vessel with the inlet for the refrigerant reactant and the sulfuric acid at its lower end and a series of inlets for the olefin reactant at vertically spaced intervals up the length of the reactor. An extended, sinuous flow path for the reactants is provided by means co-acting baffles which define sequential reaction zones in which alkylation takes place. The baffles interact with a rotary mixer with multiple impellers located on the reactor axis which provides agitation to the mixture ascending the reactor additional to that created by the ebullition of the refrigerant. Outlets for the vaporized refrigerant and the reaction effluent are provided at the upper end of the vessel. In the alkylation process operated in the reactor, the liquid isoparaffin hydrocarbon reactant/refrigerant with a sulfuric acid alkylation catalyst is introduced into the lower end of the reactor and passed along the extended reactant flow path with the olefin reactant introduced at intervals along the path. The reaction mixture flows alternately towards and away from the reactor walls in the sequence of serial reaction zones within the reactor to promote mixing of the isoparaffin reactant with the acid catalyst. With the evolution of the heat of reaction, a portion of the reactant refrigerant is vaporized to effect temperature control in the reactor. Agitation is provided by means of the rotary mixer with its mixing impellers in each of the sequential reaction zones. The vaporized reactant refrigerant and alkylation reaction products leave the reactor at its upper end.
