Abrégé

The present invention enables more effective increase in an olefin yield by means of applying a novel catalyst and reduction pretreatment to a circulating fluidized bed process, which uses a high-speed fluidized bed, and thus enhancing the selectivity and yield. By means of the reduction pretreatment, hydrocarbon is prevented from coming into contact with a catalyst during the early part of a reaction and thus is prevented from converting into an unnecessary by-product. Therefore, the conversion from the hydrocarbon to olefin is simple, the catalyst can be efficiently utilized, and unnecessary apparatuses are reduced and the facility cost can be lowered. Since the catalyst is directly heated by means of a catalytic reaction of the pretreatment process, the energy cost for increasing catalyst reaction temperature can be saved compared to the existing indirect heating. Since the number of compressor gears is reduced by means of positive pressure operation, investment cost for an apparatus is reduced.
