متن کاملConversion of Methanol on CuO/H-MOR and CuO/H-ZSM-5 Catalysts.
This paper deals with maximizing dimethyl ether (DME) production from methanol due to its industrial importance as a future diesel fuel. The high acidity and the micro-porous structure of the catalysts encouraged this reaction. Catalysts containg 6% CuO supported on H-ZSM-5 and H-MOR zeolites give high activities for DME production. The 6% CuO/HMOR is more selective for DME production, while th...
متن کاملFormation of acetone enol on acidic zeolite ZSM-5 evidenced by H/D exchange.
H/D exchange observed between bridging hydroxyl groups in acidic zeolite ZSM-5 and adsorbed acetone (acetone-d6/H-ZSM-5 and 13C-2-acetone/D-ZSM-5) indicates a concerted catalytic function of Brønsted acid sites and neighbouring framework oxygen atoms acting as Lewis base sites.
متن کاملThe Fabrication of Ga2O3/ZSM-5 Hollow Fibers for Efficient Catalytic Conversion of n-Butane into Light Olefins and Aromatics
In this study, the dehydrogenation component of Ga2O3 was introduced into ZSM-5 nanocrystals to prepare Ga2O3/ZSM-5 hollow fiber-based bifunctional catalysts. The physicochemical features of as-prepared catalysts were characterized by means of XRD, BET, SEM, STEM, NH3-TPD, etc., and their performances for the catalytic conversion of n-butane to produce light olefins and aromatics were investiga...
متن کاملMAS NMR study of the mechanism of H/D exchange for deuterated propane adsorbed on H-ZSM-5
The kinetics of hydrogen exchange between the molecules of propane-d8, propane-1,1,1,3,3,3-d6, propane-2,2-d2, and Brönsted acid sites of the zeolite H-ZSM-5 have been monitored in situ by 1H MAS NMR spectroscopy in the temperature range of 230–280 ◦C. The intramolecular hydrogen transfer was estimated by in situ 13C MAS NMR spectroscopy of the kinetics of 13C-label scrambling in adsorbed propa...
