Abstract
(EN)
The present invention relates to a circulating fluidized bed process using a catalyst for olefin production according to the present invention in a fast fluidized bed to produce olefins from hydrocarbon materials, and suggests same as an appropriate process scheme for increasing the production of olefins in a more efficient manner. According to the present invention, by using a catalyst capable of dehydrogenation reactions in a circulating fluidized bed process, and a fast fluidized region, a sufficient volume ratio and distribution of the catalyst can be further provided to allow the dehydrogenation reactions to occur, thus effectively enhancing the amount of olefins produced and maintaining an excellent yield of propylene in particular.
