William G. Billings has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Apparatus for solvent extraction of tar sands
    Patent number: 4752358
    Abstract: Tar sands are solvent extracted to form an oil-containing extract and a sandy residue. The solvent can be distilled from the oil and recycled. Residual solvent vapors can be adsorbed on an adsorbent bed. The sandy residue can be flash pyrolyzed to provide a combustible synthesis gas and/or combusted to provide process heat. Where the adsorber bed is formed from activated charcoal, a pair of beds on swing adsorption/regeneration cycles can be regenerated with steam and provide for continuous adsorption solvent vapors.
    Type: Grant
    Filed: July 3, 1986
    Date of Patent: June 21, 1988
    Assignee: Phillips Petroleum Company
    Inventor: William G. Billings

  • Zinc oxide-char gasification process
    Patent number: 4496370
    Abstract: In the gasification of char with zinc oxide, the improvement which comprises reacting the off-gas stream of gaseous zinc and carbon monoxide with steam at elevated temperatures in a second reactor means thereby oxidizing the zinc to zinc oxide and yielding a second gaseous stream containing carbon monoxide and hydrogen. This improved process avoids having to condense and revaporize the zinc, heretofore an economic barrier to the development of the zinc oxide char processes.

    Inventor: William G. Billings
  • Quenching of ZnO-char gasification
    Patent number: 4382915
    Abstract: In the gasification of char with zinc oxide improvement comprises the process of quenching the reactor effluent with recycled, cold CO product gas, thereby reducing the tendency for zinc vapor to react with any CO.sub.2 present to form blue powder.

    Inventors: Pasupati Sadhukhan, William G. Billings
  • Production of carbon monoxide from carbon
    Patent number: 4309397
    Abstract: A process for the gasification of solid carbon comprising heating under suitable conditions a feed comprising finely divided particles formed by admixing finely divided particles of solid carbon with a slurry of zinc nitrate, removing enough of the liquid of said slurry to give a solid product, calcining said solid product at a temperature no greater than about 550.degree. C. to convert a substantial portion of the zinc material to zinc oxide, and then comminuting the calcined material to the desired particle size.

  • Conversion of organic sulfides to corresponding sulfoxides
    Patent number: 4113784
    Abstract: Suitable organic sulfides are converted to the corresponding organic sulfoxides by contacting with at least one suitable hydrocarbyl sulfoxide, a protonic acid, and a suitable metal promoter. Alternatively, if hydrogen chloride is the protonic acid, graphite or suitable metal promoters can be employed.

  • Methods of converting ditertiary organic sulfides to ditertiary organic disulfides
    Patent number: 4072718
    Abstract: Ditertiary organic disulfides are produced by contacting at least one ditertiary organic sulfide with at least one suitable hydrocarbyl sulfoxide and a catalyzing amount of a protonic acid.
