Screening of Granulated Catalysts for the Dehydrogenation of Light C4 Paraffins
- 21 Downloads
Methodological aspects of the screening of granular chromia–alumina dehydrogenation catalysts are discussed, along with ways of estimating their lifetime by treating catalysts in a steam–air medium. The efficiency of using small reactors (with diameters of less than four effective granule sizes) to compare the catalytic activities of catalysts at the screening stage is demonstrated by the example of Mg- and Zr-promoted chromia–alumina catalysts.
