摘要

对沸石(Hβ、HZSM-5 和 HM)、TiO2 和 ZrO2 支持的镍钴合金催化剂进行了水相苯酚加氢脱氧试验。研究发现,催化剂的酸性对催化剂活性和产物分布有显著影响。与 NiCo/TiO2 和 NiCo/ZrO2 相比,沸石支撑催化剂脱氧产物(主要是苯和环己烷)的产率要高得多,其中环己醇和环己酮占主导地位。与 NH3-TPD 相关联,我们认为催化剂的酸性促进了加氢脱氧。Hβ 沸石支撑的镍钴合金比其他催化剂更活跃,这归因于其较高的金属分散度和较多的酸性位点。其中,在 750 oC 煅烧的 Hβ 沸石具有中等酸度,其支撑的镍钴合金催化剂(NiCo/HB-750)性能最佳。在合适的反应条件下,NiCo/HB-750 的苯酚转化率和脱氧产物总产率分别达到 96.8% 和 94.5%。

Aqueous Phase Hydrodeoxygenation of Phenol on Hβ Zeolite Supported NiCo Alloy Catalysts

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.
