Abstract: A method for producing olefins using a circulating fluidized bed process, includes: supplying a propane-containing hydrocarbon mixture and a dehydrogenation catalyst into a riser, which is a fast fluidization regime, to cause a dehydrogenation reaction; separating, from a propylene mixture, the catalyst which is a product of the dehydrogenation reaction; removing unseparated hydrocarbon compounds remaining in the catalyst separated in the separating; continuously regenerating the catalyst by mixing the catalyst stripped in the removing with a gas containing oxygen; circulating the catalyst regenerated in the continuously regenerating to the supplying and resupplying it into the riser; and preparing propylene by cooling, compressing, and separating the propylene mixture which is a reaction product separated in the separating.

Abstract: Disclosed is a catalyst for producing an olefin including an oxygen carrier material and a dehydrogenation catalyst. The catalyst allows hydrogen to be converted into water by using oxygen inside the lattice of an oxide catalyst without the additional supply of oxygen, and thus, the conversion can be increased while the decrease in selectivity, which is a disadvantage of an additional oxidative dehydrogenation reaction (ODHP), is suppressed.

Abstract: Disclosed is a method of producing an olefin using a circulating fluidized bed process, including: (a) supplying a hydrocarbon mixture including propane and a dehydrogenation catalyst to a riser which is in a state of a fast fluidization regime, and thus inducing a dehydrogenation reaction; (b) separating an effluent from the dehydrogenation reaction into the catalyst and a propylene mixture; (c) stripping, in which a residual hydrocarbon compound is removed from the catalyst separated in step (b); (d) mixing the catalyst stripped in step (c) with a gas containing oxygen and thus continuously regenerating the catalyst; (e) circulating the catalyst regenerated in step (d) to step (a) and thus resupplying the catalyst to the riser; and (f) cooling, compressing, and separating the propylene mixture, which is a reaction product separated in step (b), and thus producing a propylene product.
