How we create dehydrogenation catalysts in fluidized bed…

Development of high-performance catalyst is comparable to creative process, being often time and resources consuming, however the outcome of this challenging path offers the great opportunities…

In 1999, on the base of proprietary microspherical support AOK-63-94 the catalyst AOK-73-21 was developed for lower paraffins dehydrogenation. At that time the catalyst AOK-73-21 was classified as the most advanced catalyst for this process and in 2000 its commercial operation was started. The using of catalyst AOK-73-21 greatly improved the process, economical and environmental performances of dehydrogenation.

Catalysts for fluidized bed dehydrogenation are classified as large-scale production catalysts.  To meet the increasing demand for a new-generation catalyst of domestic manufacturers of monomers for synthetic rubber and high-octane blending fuel, including methyl tertiary butyl ether (MTBE), in 2000 the large-scale production of dehydrogenation catalyst with capacity 1000 tons per year was launched by the KATALIZATOR experts at the manufacturing site ALTAILUMINOFOR (Yarovoye, the Altai Territory).

Time passed by and new catalysts with competitive performances started to enter the market. In 2004-2007 this became a kind of driver allowing the experts to develop and start the production of improved high-stable state-of-the-art catalyst AOK-73-24 for lower paraffin dehydrogenation.

With the benefit of long-term experience in developing and mastering process technologies for the catalysts in fluidized bed, our experts and developers apply the technology of PSD adjustment of the catalyst. Thus, our company has become the unique supplier of catalysts with custom-tailored PSD and stable quality remaining unfailing from batch to the batch.

Presently, the Department of Science of Katalizator JSC is focusing on the development of dehydrogenation catalyst with improved performances. Attracting new research methods for catalyst structure and properties analysis, as well as understanding the fluidized bed dehydrogenation process allows to significantly enhance performance of the dehydrogenation catalyst. This results in creating a new grade of catalyst AOK-73-24 with resistance to regeneration high temperatures, lower amount of coke formation and ca. in 3% higher yield of the desired product, so the isobutylene production cost efficiency has been considerably increased.
