Isoparaffins are converted in a reaction zone to other hydrocarbons including isoparaffins containing fewer carbon atoms per molecule and isoparaffins containing more carbon atoms per molecule by contacting an isoparaffin feedstock with hydrofluoric acid in the presence of an amount of an olefin which is sufficient to increase the conversion of said feedstock. In a combination process said isoparaffin product containing fewer carbon atoms per molecule than the isoparaffin feedstock is passed to an alkylation zone as a portion of one of the reactants thereto. Isoparaffin product containing the same number of carbon atoms as said first-mentioned isoparaffin feedstock, and which are produced in said alkylation zone, are passed to the first-mentioned reaction zone as a portion of the feedstock thereto. Isoparaffin product containing more carbon atoms per molecule are blended with at least a portion of the hydrocarbon product produced in the alkylation zone.
The disproportionation of isopentane(s) in the presence of hydrogen fluoride as the catalyst is improved by adding at least one C.sub.6 -C.sub.18 (preferably C.sub.6 -C.sub.8) isoalkane to the isopentane feed.
A method of minimizing or controlling the production of synthetic isopentane during the catalyzed alkylation reaction of amylenes and isoparaffins by providing a concentration of isopentane in the alkylation reactor feed material.
A process for the disproportionation of pentane to alkanes containing fewer carbon atoms per molecule and alkanes containing more atoms per molecule in the presence of a catalyst composition containing hydrogen fluoride (HF), titanium tetrafluoride (TiF.sub.4) and sulfolane.
A process for disproportionating isoparaffins and paraffins in the presence of at least one initiator is disclosed. The product from the disproportionation contains a gasoline range material having a higher octane-rating than the isoparaffins and paraffins in the feed and a diesel range material having a higher cetane number than the isoparaffins and paraffins in the feed.
An apparatus for removing low density liquids from oil production water tanks. The apparatus includes a vertically disposed elongated hollow base member having an upper end and a lower end, the base member having at least two radially spaced mounting bosses affixed in a horizontal plane thereto at a distance between the upper and lower ends of the base member; a plug mounted at the upper end of the base member; a hollow inlet member having a first end and a second end, the first end mounted to the lower end of the base member, the inlet member further having a substantially horizontally disposed fluid inlet in fluid communication with at least the second end of the inlet member; at least two substantially horizontally disposed arms, the arms each having a first end and a second end, the first end of each being mounted to the radially spaced mounting bosses of the base member; at least two hollow float members each of the float members having a connecting boss mounted thereon, the connecting bosses of the float members connected to the second end of the arms; and an elongated flexible tubular member having a first end and a second end, the first end in fluid communication with the second end of the hollow inlet member.
