Pilot Testing of the Microspherical Aluminochromium KDI-M Catalyst for Isobutane Dehydrogenation

Abstract

Results of pilot testing of the microspherical aluminochromium KDI-M catalyst mixed with IM-2201 in a large-scale unit (Nizhnekamskneftekhim) for isobutane dehydrogenation are discussed. Against the KDI catalyst, its modified analogue KDI-M is more active and selective; the optimizedgrain-size composition and mechanical strength provides an improved isobutylene yield and a longer non-stop operation (up to 400 days) of the reactor unit.
