    摘要: Catalysts for oxidative dehydrogenation of alkane to one or more olefins, exemplified by ethane to ethylene, are disclosed. The catalyst comprises a mixture of metal oxides having as an important component nickel oxide (NiO) and gives high conversion and selectivity. For example, the catalyst can be used to make ethylene by contacting it with a gas mixture containing ethane and oxygen. The gas mixture may optionally contain ethylene, an inert diluent such as nitrogen, or both ethylene and an inert diluent.

    摘要: A method for converting levulinic acid to methyl vinyl ketone is described. The method includes the steps of reacting an aqueous solution of levulinic acid, over an acid catalyst, at a temperature of from room temperature to about 1100 K. Methyl vinyl ketone is thereby formed.
