  • Lead-zirconate catalysts
    Patent number: 5082816
    Abstract: Catalysts comprising lead doped zirconium compounds are particularly effective in an oxidative process for upgrading low molecular weight alkanes to higher molecular weight hydrocarbons, and especially for upgrading methane to form ethane and ethylene. The catalysts can be employed in a process performed at elevated temperatures and in the presence or absence of gaseous oxygen. The catalysts are substantially free of PbO and uncombined Pb and remain stable for long periods of time.
    Type: Grant
    Filed: July 23, 1990
    Date of Patent: January 21, 1992
    Assignee: The Standard Oil Company
    Inventors: Raymond G. Teller, James F. Brazdil, Jr., Joseph P. Bartek, Ann M. Brussee
