- 中文摘要: 本研究是探討P-1, P-2, P-2W與DBNi硼化鎳觸媒於一氧化碳氫化反應之催化行為, 包括將鉻促進劑引入 P-1硼化鎳以瞭解鉻的影響, 以及為增進觸媒之穩定度與分散性將 P-1或CrP-1 硼化鎳固著於擔體上以瞭解擔體的效應。一般而言P-1, P-2及 P-2W硼化鎳之一氧化碳氫化活性不及商業化倫尼鎳觸媒, 但DBNi硼化鎳卻有很好的活性。鉻不但顯著地增進活性也增進高碳烴產物之選擇率。將 P-1固著於Niobia所得之P-1/Niobia觸媒有非常好的穩定度,並且與一般Ni/Niobia觸媒一樣具有顯著的 SMSI行為。
- 英文摘要: The catalytic behaviors of various nickel boride catalysts in CO hydrogenation were investigated. The chromium was introduced into P-1 nickel boride to examine its effects on CO hydrogenation. The P -1 nickel boride was also supported on active carbon, Florisil and Niobia to increase the dispersion and stability of it. Generally the P-1, P-2 and P- 2W nickel borides were less active than commercial Raney nickel, but the DBNi nickel boride was more active than it. The promoter of chromium not only effectively promoted the activity of P-1 nickel boride but also shifted the product distribution to higher hydrocarbons. The P-1/Niobia catalysts exhibited SMSI behaviors in CO hydrogenation like Ni/Niobia catalysts, and good stability.
