Abstract: The present invention relates to a temperature-change sensing substrate comprising a self-healing polyurethane polymer. More specifically, the present invention relates to a temperature-change sensing substrate having a self-healing polyurethane polymer matrix and a plurality of pores dispersed in the matrix. The temperature-change sensing substrate according to the present invention can be applied as a temperature-change sensor for preventing the spoiling of refrigerated or frozen food and medical supplies. For example, substrate, which was opaque when stored at −60° C., −50° C., −30° C., −20° C., −10° C. and the like, becomes transparent if the temperature rises to 0° C., 10° C., 20° C., 30° C. and the like, and thus a temperature-change sensor capable of checking storage conditions through a change in light transmittance can be provided.

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.
