ABSTRACT:
Disclosed is a device for the production of alkylate(s) by sulfuric acid alkylation of at least one isoparaffin such as isobutane with at least one olefin, such as butylenes. The device includes a mixing chamber for preparing a mixture of the isoparaffin with recycled reaction products. It also includes an emulsion chamber for preparing a first hydrocarbons-in-sulfuric acid emulsion, where the mixture prepared in the mixing chamber is injected in multiple parallel jets into a sulfuric acid composition. The device further includes a pre-reaction chamber for preparing a second emulsion, where a given portion of the olefin is injected in jet streams into the first hydrocarbons-in-sulfuric acid emulsion coming from the emulsion chamber. Last of all, the device includes a reaction chamber of given height and cross-section where the second emulsion coming from the pre-reaction chamber is injected through nozzles and another portion of olefin is injected in jet streams all over the cross-section and height of the reaction chamber. The reaction chamber is devised so that the second emulsion is circulated in a closed circuit and it has an outlet through which a balanced amount of reaction mixture is continuously discharged. All of said mixing chamber, emulsion chamber, pre-reaction chamber and reaction chamber are coaxially arranged one above the other in vertical position and altogether form a reactor with the prechamber being located at the bottom of the reactor and the reaction chamber on top thereof. A method for the production of alkylates by means of the above device is also disclosed.
