  • Process for producing synthetic fuel gas by reacting liquid hydrocarbons with hydrogen
    Patent number: 4302219
    Abstract: Process for producing synthetic fuel gas from either naturally occurring or synthetic liquid hydrocarbons by reacting the liquid hydrocarbons with hydrogen in the presence of a catalyst to produce methane. The catalyst comprises an interspersed mixture of metals selected from Groups IV(B), V(B), or VI(B) in combination with two Group VIII metals, composited with an inorganic refractory oxide support.
    Type: Grant
    Filed: December 5, 1980
    Date of Patent: November 24, 1981
    Assignee: Union Oil Company of California
    Inventors: Howard D. Simpson, Hugh W. Gowdy, Steven D. Light
  • Methanation catalysts and process for their preparation
    Patent number: 4284531
    Abstract: Methanation catalysts and process for preparing and using the same are disclosed; said methanation catalysts being especially suitable for producing synthetic fuel gas, from either naturally occurring liquid hydrocarbons or synthetic liquid hydrocarbons produced from solid carbonaceous materials, the product gas having substantially the same heating value and density as natural gas and which may be intermingled therewith and distributed through the same pipe lines.The methanation catalyst comprises an interspersed mixture of metals selected from Groups IV(B), V(B), VI(B) and VIII metals of the Periodic Table, composited with an inorganic refractory oxide support or matrix.
    Type: Grant

  • Aromatization process and catalyst
    Patent number: 4193895
    Abstract: Paraffinic, olefinic and naphthenic hydrocarbons are converted to aromatic hydrocarbons by contacting the same at elevated temperatures with a catalyst comprising an alumina-supported composite of platinum, chlorine and a minor proportion of cesium, with or without other added metals such as iridium, rhodium, rhenium and the like.
