  • Lead-tolerant catalyst system and method for treating exhaust gas containing lead compounds
    Patent number: 4702897
    Abstract: A lead-resistant exhaust gas oxidation catalytic composite is disclosed. The composite comprises a support material comprising a refractory inorganic oxide having deposited thereon a catalytic component selected from the Group consisting of platinum, palladium, iridium, rhodium and mixtures thereof and having dispersed thereover a protective coating of zirconia. Also disclosed is a method for effecting oxidation of noxious exhaust gases comprising hydrocarbons, carbon monoxide and lead compounds. Additionally, a method for oxidizing an exhaust gas from an internal combustion engine operating upon leaded fuel is also disclosed.
    Type: Grant
    Filed: September 30, 1985
    Date of Patent: October 27, 1987
    Assignee: Signal Applied Technologies, Inc.

  • Lead-tolerant catalyst for treating exhaust gas in the presence of SO.sub.2
    Patent number: 4650782
    Abstract: A lead-tolerant exhaust gas oxidation catalytic composite for oxidizing gas in the presence of SO.sub.2 comprising a refractory inorganic oxide support material having deposited thereon a noble metal component and having dispersed thereon a protective coating of titania. The refractory support material may be deposited with a noble metal and thereafter applied as a washcoat on a low surface area support matrix followed by a titanium washcoat superimposed thereover. Also, a method for treating exhaust gases containing lead components by contacting the exhaust gas with the catalytic composite is disclosed.
