Bismuth Molybdate 촉매상에서의 1-Butene의 산화 탈수소 반응
The Oxidative Dehydrogenation Reaction of 1-Butene over Bismuth Molybdate Catalyst
산성 용액과 염기성 용액으로부터 공침범에 의하여 각각 α,β 및 γ-phase의 bismuth molybdate 촉매를 제조하여 촉매의 특성을 분석하고 450-530℃의 온도범위에서 1-butene의 산화 탈수소 반응실험을 수행하였다. 활성이 가장 우수한 것으로 관찰된 γ-phase 촉매를 대상으로 여러 반응온도 및 반응물 조성의 조건하에서 반응실험을 수행한 결과 490-530℃의 온도범위에서는 산소와 1-butene이 서로 다른 흡착점에 흡착하여 반응이 진행되는 dual site Langmuir-Hinshelwood 반응기구를 따르는 것으로 나타났으며 이에 대응하는 반응속도식을 결정하였다.
The bismuth molybdate catalysts were prepared in three different types(α,β and γ-phases) by the method of coprecipitation from acid solution of from alkaline solution. The catalysts were than character-ized and applied for the oxidative dehydrogenation reaction of 1-butene in the range from 450℃ to 530℃. Reaction experiments were conducted with the γ-phase catalyst, showing the best activity, under the conditions of various reaction temperatures and various reactant compositions. By analyzing the experimental results it was confirmed that, in the temperature range from 490℃ to 530℃, the reaction proceeds via the dual site Langmuir-Hinshelwood mechanism with two different adsorption sites for oxygen and 1-butene, where the surface reaction is rate-determining, and the corresponding rate equation was determined.
