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.

Abstract: Disclosed is a process for the alkylation of an olefin with an isoparaffin using sulphuric acid as a catalyst. In this process, a finely-dispersed emulsion of isoparaffin and sulphuric acid is prepared first, in a separate emulsion preparation zone. This preparation is carried out by injecting the isoparaffin into the acid through a set of nozzles, thereby allowing the isoparaffin to "scavenge" at high speed through the acid and thus to form an extremely homogeneous emulsion. This makes it possible to achieve proper mixing without need of impellers or other similar mixing devices that usually call for substantial maintenance and operating costs. Then, the emulsion that was so prepared and which forms an already "finished" phase per se, is fed into a reaction zone which is separate from the emulsion preparation zone and in which the olefin is injected preferably at a plurality of points and in directions perpendicular to the emulsion flow.
