  • Publication number: 20060278568
    Abstract: A process for the removal of oxygenated sulfur compounds from a hydrocarbon stream, especially the effluent from a sulfuric acid alkylation reactor, in which the hydrocarbon stream is first subjected to deentrainment of any carryover liquid sulfuric acid and then passed over a sorbent which removes the oxygenated sulfur compounds.

  • Publication number: 20060270885
    Abstract: A process for the isomerization of heptane preferably contained within a naphtha stream is disclosed wherein the naphtha is stripped of the butanes and the pentanes and hexanes are removed for isomerization. The heptanes and heavier are fed to a distillation column reactor containing an isomerization catalyst where the normal heptane is isomerized to mono and di branched heptane and removed as overheads. The cyclic heptanes and heavier are removed as bottoms and for feed to a catalytic reforming process.

  • Publication number: 20060264318
    Abstract: A catalytic material includes microporous zeolites supported on a mesoporous inorganic oxide support. The microporous zeolite can include zeolite Beta, zeolite Y (including “ultra stable Y”—USY), mordenite, Zeolite L, ZSM-5, ZSM-11, ZSM-12, ZSM-20, Theta-1, ZSM-23, ZSM-34, ZSM-35, ZSM-48, SSZ-32, PSH-3, MCM-22, MCM-49, MCM-56, ITQ-1, ITQ-2, ITQ-4, ITQ-21, SAPO-5, SAPO-11, SAPO-37, Breck-6, ALPO4-5, etc. The mesoporous inorganic oxide can be e.g., silica or silicate. The catalytic material can be further modified by introducing some metals e.g. aluminum, titanium, molybdenum, nickel, cobalt, iron, tungsten, palladium and platinum. It can be used as catalysts for acylation, alkylation, dimerization, oligomerization, polymerization, hydrogenation, dehydrogenation, aromatization, isomerization, hydrotreating, catalytic cracking and hydrocracking reactions.

  • Publication number: 20050197499
    Abstract: An integrated process combines olefin epoxidation with production of cyclohexanone and cyclohexanol for nylon. Cyclohexanone and cyclohexanol normally produced by the oxidation of cyclohexane, in which cyclohexyl hydroperoxide is generated and is removed or decomposed down stream. However, this invention utilizes the intermediate of cyclohexyl hydroperoxide as an oxidant for the olefin epoxidation and meanwhile generates a valuable product.

  • Publication number: 20030073875
    Abstract: An integrated process for upgrading a mixed C4 or mixed C5 alkane/isoalkane stream first separates the iso from the normal alkane by distillation. Then a portion of the normal alkane is dehydrogenated to the corresponding alkene. The isoalkane and normal alkene are then fed to an alkylation unit where they are reacted together to form a branched chain alkane having a desirable octane number. If desired a portion of the separated normal alkane may be skeletally isomerized to additional isoalkane.
