The development of catalysts for dehydrogenation of lower C3-C4 paraffins using the products of gibbsite thermal activation

Propane chlorination over ruthenium oxychloride catalysts

“…The direct catalytic dehydroge nation of propane is carried out in the presence of metal oxides, namely, Cr 2 O 3 , MoO 3 , V 2 O 5 , TiO 2 , and GeO 2 . The most efficient catalyst is Cr 2 O 3 supported on γ Al 2 O 3 [2][3][4]. The industrial processes are con ducted at ∼550-600°C.…”

Propylene production technology: Today and tomorrow

“…For propane dehydrogenation by this technology, a special KDN catalyst was developed [67]. A version of the propylene production process was tested on a demonstration unit, but is not used on an industrial scale today.…”

Recycling of Wastes from the Production of Alumina-Based Catalyst Carriers

“…The FBD technology imposes several requirements for the catalysts, not only in terms of activity, but also in terms of abrasion resistance. A chromia–alumina catalyst developed rather recently at Boreskov Institute of Catalysis (Novosibirsk, Russia), together with an industrial company (Sintez, in Barnaul, Russia) fulfills these requirements, exhibiting high activity, selectivity, and mechanical strength. − At the present time, the catalyst under the tradename KDM is applied in many industrial plants. The first industrial experience, briefly summarized in ref , focuses on a substantial decrease in the nominal catalyst consumption, which, in fact, is a serious issue.…”
