Abstract: According to one or more embodiments of the present disclosure, a method for producing olefins includes contacting a hydrocarbon-containing feed with a catalyst in a reactor portion of a reactor system to form an olefin-containing effluent, separating at least a portion of the olefin-containing effluent from the catalyst, passing the catalyst to a catalyst-processing portion of the reactor system and processing the catalyst to produce a processed catalyst and a combustion gas, passing the processed catalyst from the catalyst-processing portion to the reactor portion, and introducing a combustion additive to the reactor system when the combustion gas comprises one or more hydrocarbons in an amount greater than 5% of an LFL of the combustion gas at a temperature and pressure of the catalyst processing portion. The catalyst may include from 1 ppmw to 150 ppmw platinum. The combustion additive may include from 150 ppmw to 1,000 ppmw platinum.

Abstract: According to one or more embodiments of the present disclosure, a catalyst system useful for dehydrogenation includes from 98 vol. % to 99.95 vol. % of a catalyst and from 0.05 vol. % to 2 vol. % of a combustion additive. The catalyst may include from 1 ppmw to 150 ppmw platinum, gallium, and a support material. The combustion additive may include from 150 ppmw to 1,000 ppmw platinum, gallium, and a support material. The combustion additive may include at least 1.1 times greater platinum than the catalyst.
