Abstract: A microspherical chromium oxide/alumina catalyst (KDM) has been developed for fluidizedbed isobutane dehydrogenation. This catalyst shows a high catalytic activity, selectivity, and thermal stability. The KDM preparation technology involves an alumina support produced by centrifugal thermal activation (CTA) of gibbsite—CEFLARTM technology. This technology makes it possible to regulate the phase composition of the CTA product in a wide range and to synthesize, from this product, supports with preset structural and textural properties. The support and catalyst production technologies have been commercialized by Altailyuminofor Co. Since 2008, the KDM catalyst has been employed by SIBUR Holding Co. and Ekooil Co. (Omsk). Industrialscale application of the catalyst has demonstrated that isobutane dehydrogenation over an IM2201 + KDM mixture reduces the catalyst consumption (kg/(t isobutylene)) from 22–23 for pure IM2201 to 8–9.5 for the IM2201 + KDM mixture. For further improvement of the KDM catalyst, fundamental studies of the nature of the active component of this catalyst have been carried out: the role of different states of supported chromium oxide species in dehydrogenation has been elucidated and approaches to controlling the proportion of active and selective chromium oxide species have been devised. These studies have culminated in the development of a catalyst modification whose activity and selectivity exceeds the same characteristics of the original KDM catalyst by 2–4 wt %.
