Aqueous Phase Hydrodeoxygenation of Phenol on Hβ Zeolite Supported NiCo Alloy Catalysts
Zeolites (Hβ, HZSM-5 and HM), TiO2 and ZrO2 supported NiCo alloy catalysts were tested for the hydrodeoxygenation of phenol in aqueous phase. It has been found that the catalyst acidity remarkably influences the catalyst activity and the product distribution. Zeolites supported catalysts give much higher yield of the deoxygenated products (mainly benzene and cyclohexane) than NiCo/TiO2 and NiCo/ZrO2, where cyclohexanol and cyclohexanone are dominating. Associated with NH3-TPD, we suggest that the catalyst acidity promotes the hydrodeoxygenation. Hβ zeolite supported NiCo alloy is more active than others, attributed to its higher metal dispersion and more acid sites. Therein, the Hβ zeolite calcined at 750 oC has moderate acidity, and its supported NiCo alloy catalyst (NiCo/HB-750) shows the best performance. Under a suitable reaction condition, the phenol conversion and the total yield of deoxygenated products reaches 96.8% and 94.5% on NiCo/HB-750, respectively.
期刊介绍：
Early dissemination of important findings from Asia which may lead to new concepts in catalyst design is the main aim of this journal. Rapid, invited, short reviews and perspectives from academia and industry will constitute the major part of Catalysis Surveys from Asia . Surveys of recent progress and activities in catalytic science and technology and related areas in Asia will be covered regularly as well. We would appreciate critical comments from colleagues throughout the world about articles in Catalysis Surveys from Asia . If requested and thought appropriate, the comments will be included in the journal. We will be very happy if this journal stimulates global communication between scientists and engineers in the world of catalysis.
