  • Process of oxidizing aliphatic hydrocarbons employing a molybdate catalyst composition
    Patent number: 5146031
    Abstract: A process for the production of olefins and diolefins, such as 1,3-butadiene, comprising contacting an aliphatic hydrocarbon, such as butane, with a heterogeneous catalyst composition containing reactive oxygen under reaction conditions such that a more highly unsaturated aliphatic hydrocarbon is selectively formed in a high productivity. The catalyst is a composition comprising (a) a support component of magnesia and alumina and/or magnesium aluminate spinel, and (b) a catalyst component of magnesia, an oxide of molybdenum, a Group IA metal oxide promoter, and optionally vanadium oxide. Catalysts of high surface area and high attrition resistance are claimed.
