  • Process for the production of mono-olefins
    Patent number: 5105052
    Abstract: Process for the production of a mono-olefin from a gaseous paraffinic hydrocarbon having at least two carbon atoms or a mixture thereof. The process includes the step of partially combusting, in contact with a combustion catalyst, the gaseous paraffinic hydrocarbon or a mixture of the gaseous paraffinic hydrocarbons and a molecular oxygen-containing gas in a composition of from 5 to 9 times the stoichiometric ratio of hydrocarbon to oxygen for complete combustion of carbon dioxide and water. In the process, the mixture is partially combusted at a temperature in the range of 500.degree. to 1200.degree. C. and at a gas hourly space velocity of at least 80,000 hr.sup.-1.

  • Process for the production of mono-olefins by the catalytic oxidative dehydrogenation of gaseous paraffinic hydrocarbons having two or more carbon atoms
    Patent number: 4940826
    Abstract: A process for preparing mono-olefins by catalytic oxidative dehydrogenation of e.g. ethane, propane or butanes is provided. The process employs a catalyst which is capable of supporting combustion beyond the normal fuel rich limit of flammability. Preferred catalysts are platinum group metals supported on a monolith e.g. platinum.
