Description

technical field

[0001] The invention relates to a cobalt-based single-atom dehydrogenation catalyst and a method for preparing corresponding olefins from paraffins using the catalyst. More specifically, the present invention relates to a dehydrogenation catalyst and a preparation method thereof. In the dehydrogenation catalyst, the inorganic oxide (specifically silicon dioxide) of the alkali metal in the form of a single atom is fixed on the support body through the pretreatment of the alkali metal Cobalt is loaded with a single atom, and relates to a method of dehydrogenating paraffins, in particular light paraffins, to prepare corresponding olefins in the presence of the dehydrogenation catalyst. Background technique

[0002] Light olefins such as ethylene, propylene, butylene are widely used in the petrochemical industry and are used as chemical products (oxo-alcohol, acrylonitrile, propylene oxide, butanol, acrylic acid, etc.) and plastic products Important chemical raw...
