Ordered mesoporous carbon catalyst for dehydrogenation of propane to propylene.
Metal-free ordered mesoporous carbons were demonstrated to be robust catalysts for direct dehydrogenation of propane to propylene, in the absence of any auxiliary steam, exhibiting high activity and selectivity, as well as long catalytic stability, in comparison with nanostructured carbons.
متن کاملPropane Dehydrogenation with Better Stability by a Modified Pt-Based Catalyst
The effect of transition metal doping on Pt/Al2O3 catalyst used in propane dehydrogenation reaction at 500 ̊C was studied. The preparation methods investigated were sequential impregnation (Pt followed by the 2 metal or the 2 metal followed by Pt) and co-impregnation. The metal contents of these catalysts were fixed as the weight ratio of Pt per the 2 metal of around 0.075. These catalysts were ...
متن کاملCharacterization of pore coking in catalyst for thermal down-hole upgrading of heavy oil
Heavy oil and bitumen are a potential alternative energy source to conventional light crude. However, recovery of these resources can have substantial environmental impact. Downhole upgrading offers the prospect of both improving recovery, and decreasing environmental impact. However, use of catalysts to enhance downhole upgrading is limited by the need for one that can survive the extreme coki...
متن کاملThe Effect of Alkali Metal Promoters on the Stability and Coke Formation of Platinum-Based Propane Dehydrogenation Catalysts: A Kinetic Study
The kinetics of catalyst deactivation and coke formation during dehydrogenation of propane over supported Pt–based catalysts and, in particular, the effect of alkali metal promoters on catalyst activity and stability were studied. The analysis of propane conversion data showed that there is an optimum level of alkali metal promoter loading for both catalyst activity and stability.A model ba...
متن کاملCatalyst deactivation
The fundamentals of catalyst deactivation are presented in this review. The chemico-physical aspects concerning the various deactivation causes (i.e. poisoning, sintering, coking, solid-state transformation, masking, etc.) have been analyzed and discussed, along with the mathematical description of the deactivation phenomena. # 1999 Elsevier Science B.V.
