CDM series microspherical catalysts for fluidized bed dehydrogenation of paraffins


кдм.jpg

The microspherical aluminochromium catalysts are prepared using nanostructured products of the centrifugal thermal activation (CTA) of gibbsite. The technology allows the porous structure of the support, dispersion of the active component (<3 nm) and fraction composition of the catalysts to be controlled in order to provide their improved activity, selectivity and mechanical strength during operation.
