摘要： An intentionally produced low octane value alkylate is reformed in the presence of steam, and in the absence of added hydrogen, to produce a high octane value, olefinic reformate containing aromatics. The reformate, upon fractionation to remove hydrogen and methane and C.sub.3 and C.sub.4 hydrocarbons, which can be recycled, is subjected to solvent extraction to produce a raffinate which can be used as high octane gasoline and which contains olefins, and an extract which, upon fractionation to remove xylenes therefrom as usable product, and which now contains benzene and toluene, can be combined with said raffinate.

摘要： In an HF alkylation process, ASO is separated from HF acid catalyst in a fractionation zone by heating the fractionation zone with a condensible stream comprising liquid and vaporous components. In the process of condensation, latent heat is evolved which is used to effectuate the separation of ASO and HF acid catalyst and dilution of the separated ASO is achieved with the use of the produced condensate.

摘要： The time for effecting separation of HF acid-hydrocarbon emulsions is substantially decreased by adding a finite amount of up to about 700 ppm of a tetraalkylammonium iodide coalescing promoter to the emulsion. The rapid separation of HF acid-hydrocarbon emulsions comprising reaction effluent obtained from alkylation processes is facilitated by the addition of a tetraalkylammonium iodide to the reaction effluent prior to phase separation.

摘要： A apparatus for the catalytic alkylation of an isoparaffin with one or more olefins. Reactant hydrocarbons are passed in contact with a liquid catalyst such as hydrofluoric acid in a reaction zone. The hydrocarbon phase is allowed to separate from the catalyst phase in a settling zone, and a portion of the hydrocarbon phase is cooled and reintroduced to the reaction zone in a separate stream from that of the feed hydrocarbons. The alkylation apparatus by which the process is carried out includes a vertical reaction vessel, which in a preferred embodiment is 2 to 6 feet in height, a settling vessel, means for fluid flow from the reaction vessel to the settling vessel, a conduit for fluid flow between the upper part of the settling vessel and the reaction zone, and means for cooling fluid in this conduit.
