  • Patent number: 8450545
    Abstract: A process of modifying a zeolite catalyst to produce a modified zeolite catalyst wherein the modified zeolite catalyst has blocked pore sites. An oxygenated feed is flowed over the modified zeolite catalyst, wherein the oxygenated feed comprises hydrocarbons, methanol and dimethyl ether or a mixture thereof. The hydrocarbons, methanol and dimethyl ether in the oxygenated feed react with the modified zeolite catalyst to produce cyclic hydrocarbons, wherein the cyclic hydrocarbons produced has less than 10% durene and a median carbon number is C8.

  • Patent number: 8268745
    Abstract: A silicate-resistant sorbent composition, as well as a method of making and using the same, is provided. The sorbent composition generally comprises a support component comprising one or more silicate-resistant silica-containing components that have been treated one or more silicate-inhibiting metals. The inventors have discovered that sorbent compositions made and used according to embodiments the present invention exhibit a surprisingly low in situ silicate generation rate when exposed to oxidative regeneration conditions.

  • Patent number: 7955576
    Abstract: A composition, containing vanadium and a support, wherein at least a portion of the vanadium has crystallite sizes of less than about 100 ? as determined by an analytical method such as X-Ray Diffraction, is disclosed. A method of preparing such composition is also disclosed. The composition is employed in a process to remove a heavy metal from a gaseous feed stream which can optionally include a separate mercury adsorption stage.

    Date of Patent: June 7, 2011
    Assignee: ConocoPhillips Company
    Inventors: Joseph B. Cross, Glenn W. Dodwell, Marvin M. Johnson, Edward L. Sughrue, II, Jianhua Yao
  • Patent number: 7955588
    Abstract: Methods and apparatus relate to catalysts and preparation of the catalysts, which are defined by sulfides of a transition metal, such as one of molybdenum, tungsten, and vanadium. Precursors for the catalysts include a metal ion source compound, such as molybdenum trioxide, and a sulfide ion source compound, such as thioacetamide. Once the precursors are dissolved if solid and combined in a mixture, homogenous precipitation from the mixture forms the catalysts. Exemplary uses of the catalysts include packing for a methanation reactor that converts carbon monoxide and hydrogen into methane.

    Inventors: Madhu Anand, Brian C. Dunn, Glenn W. Dodwell
  • Patent number: 7951740
    Abstract: A method for regenerating desulfurization sorbents that minimizes the in situ formation of one or more silicates. It has been discovered that regenerating sulfur-laden sorbent particles in a carbon oxide-rich environment unexpectedly reduces the in situ silicate formation rate, as compared to similar sorbents regenerated using conventional methods.
