  • Publication number: 20200086300
    Abstract: Disclosed are a catalyst for producing olefin and a preparation method thereof. The catalyst for producing olefin includes: a support including an alumina and a sub-support component; and a catalytic component comprising a metal component and an alkali metal impregnated on the support. The preparation method includes: providing a support comprising a sub-support component and an alumina; preparing pre-catalyst by dipping a metal component oxide in the support and calcining it; and dipping a metal component oxide and an alkali metal oxide in the pre-catalyst and calcining it.

  • Publication number: 20190388884
    Abstract: Disclosed is an olefin production method including: pretreating a catalyst by providing reduction gas to an alumina type catalyst to produce olefin from the hydrocarbon including not less than 90 wt % of LPG (Stage 1); producing the olefin by providing the catalyst pretreated at Stage 1 into Riser of Fast Fluidization Regime to dehydrogenate the hydrocarbon (Stage 2); separating the mixture of the produced propylene and the catalyst used at Stage 2, and regenerating the separated catalyst (Stage 3); and recycling the catalyst regenerated at Stage 3 to the process of Stage 1 (Stage 4).

  • Publication number: 20190330125
    Abstract: Disclosed is an olefin production method which includes: (a) providing the regenerated catalyst and the hydrocarbon including not less than 90 wt % of LPG into Riser of Fast Fluidization Regime, and dehydrogenating in the presence of an alumina type catalyst; (b) separating an effluent from the dehydrogenation reaction into the catalyst and propylene mixture; (c) stripping to remove the hydrocarbon compound included in the catalyst separated at stage (b); (d) mixing the catalyst stripped at stage (c) with the gas including oxygen, and continuously regenerating it; (e) recycling the catalyst regenerated at stage (d) to stage (a), and providing it again into Riser; and (f) producing propylene product by cooling, compressing and separating propylene mixture of the reaction product separated at stage (b).
