Abstract: Contacting apparatus chamber having a grid structure positioned therein, characterized by downwardly projecting frustoconic shaped nozzles, which extend below the lower face of the plate defining ''''dead spaces'''' in between the nozzles. The nozzle walls diverge at an angle no greater than 30* and preferably at an angle of about 3* to about 6*, measured from the vertical axis of the nozzle. This grid structure permits smooth flow of materials through the grid thereby avoiding fouling of the grid.

Abstract: The present invention provides an improved alkylation process comprising: contacting an olefin and a paraffin with an alkylation catalyst comprising fluorosulfuric acid, at alkylation conditions, in an alkylation reactor, thereby forming a hydrocarbon phase comprising alkylate reactor product and containing at least a portion of the catalyst; washing the hydrocarbon phase with an acid comprising sulfuric acid to form an acid phase containing fluorosulfuric acid, hydrofluoric acid, and sulfuric acid; contacting the acid phase with water thereby converting at least a portion of the fluorosulfuric acid to hydrogen fluoride and sulfuric acid; removing at least a portion of the hydrogen fluoride from the acid phase by contacting the same with a paraffin such as n-butane thereby forming a hydrocarbon phase containing hydrogen fluoride; treating the hydrocarbon phase with sulfur trioxide to regenerate the fluorosulfuric acid; and recycling at least a portion of the regenerated fluorosulfuric acid to the alkylation zone to be used as an alkylation catalyst therein.

Abstract: Waxy oil is dewaxed by shock chilling with prechilled solvent under conditions of agitation sufficient to obtain substantially instantaneous mixing at a plurality of points along the length of a vertical tower wherein the velocity of solvent injection is at least 5 to 10 times that of the peripheral velocity of the mixer blades.
