  • Process for converting triglycerides to hydrocarbons
    Patent number: 7550634
    Abstract: Processes for the conversion of hydrocarbons boiling in the temperature range of from about 80° F. to about 1000° F. to diesel boiling range hydrocarbons, and processes for increasing the cetane number and amount of n-C17 hydrocarbon products in such processes. Diesel boiling range hydrocarbons may be produced by contacting a hydrocarbon boiling in the above-mentioned boiling range with a triglyceride-containing compound to form a mixture, and then contacting the mixture with a hydrotreating catalyst under suitable reaction conditions.
    Type: Grant
    Filed: January 30, 2006
    Date of Patent: June 23, 2009
    Assignee: ConocoPhillips Company

  • Fluid catalytic cracking process
    Patent number: 5637207
    Abstract: An intermediate distillate fraction is subjected to fluid catalytic cracking (FCC) to yield liquid fuel and lighter. The C.sub.7 -C.sub.10 paraffin lift fluid is converted to C.sub.2 -C.sub.5 olefins and naphtha of enhanced octane.

    Assignee: ABB Lummus Global Inc.
    Inventors: Hsu-Hui Hsing, Jonathan P. Rich, Glenn A. Clausen
  • Heavy naphtha hydroconversion process
    Patent number: 5624548
    Abstract: A straight run naphtha is fractionated to yield on intermediate naphtha and the heaviest 10-25 vol % as heavy naphtha. The heavy naphtha is subjected to hydrocracking to yield liquid fuel and lighter, including C.sub.4 isoparaffins and a cracked naphtha having a 90 vol % temperature (T90) of 310.degree. F. (155.degree. C.).

  • Hydrocarbon cracking process employing zeolite catalysts with hybrid [A1,B]-zeolite additives
    Patent number: 5395512
    Abstract: A hydrocarbon feedstock is catalytically cracked at an elevated temperature in a cracking zone with a zeolite cracking catalyst. The cracking catalyst employed comprises a crystalline aluminosilicate zeolite catalyst and a hybrid [Al,B]-zeolite catalyst. In this process the hydrocarbon feedstock is contacted with the zeolite catalyst in, for example, a fluidized bed catalytic cracking unit to yield cracked products containing increased amounts of C.sub.3 /C.sub.8 olefins.

  • Fluid catalytic cracking process yielding hydrogen
    Patent number: 5362380
    Abstract: In a fluid catalytic cracking (FCC) process coked catalyst is partially regenerated by contacting with high temperature steam in the absence of oxygen. About 10 to 30% of the coke is converted to a steam reformed gas comprising hydrogen, methane and carbon dioxide. The off-gas may be subjected to cryogenic separation to yield a hydrogen-rich gas.

  • Heavy naphtha conversion process
    Patent number: 5318689
    Abstract: A straight run naphtha is fractionated to yield on intermediate naphtha and the heaviest 10 vol % as heavy naphtha. The intermediate naphtha is catalytically reformed to yield reformed naphtha having a 90 vol % temperature (T90) of 310.degree. F. (155.degree. C.). The heavy naphtha is subjected to fluid catalytic cracking (FCC) to yield liquid fuel and lighter, including C.sub.4 olefins and a cracked naphtha having a research octane number suitable for gasoline blending.

  • Al.sub.2 O.sub.3 alkene isomerization process and catalyst
    Patent number: 5043523
    Abstract: Gamma alumina having a sodium content of less than 0.01 weight percent sodium calculated as Na.sub.2 O and said alumina modified with silicon were found to be superior catalysts for the isomerization of alkenes having at least four carbon atoms, preferably with 0.01 to 1 mole of water per mole of alkene present during the isomerization. Both skeletal isomerization (e.g. n-butene to isobutene) and position isomerization (e.g. butene-2 to butene-1) are obtained.
