  • Process for preparing a supported catalyst for the oxydehydrogenation of ethane to ethylene
    Patent number: 4596787
    Abstract: A process for low temperature oxydehydrogenation of ethane to ethylene uses an improved supported catalyst produced by impregnating the support with the soluble portion of a precursor catalyst solution and then activating the impregnated support. The activated impregnated support provides good selectivity to ethylene and avoids the problems which can arise from impregnation of the support with the soluble and insoluble portions of a precursor catalyst solution.
