초록

프로판의 아크릴로니트릴로의 가암모니아 산화반응을 Nb₂O₅-V_0.4Mo₁Te_0.1 혼합촉매를 이용하여 연구하였다. 가암모니아 산화반응의 촉매적 활성은 강한 산성을 띠는 니오피움산화물을 몰리브덴계 산화물촉매(V_0.4Mo₁Te_0.1)에 첨가함에 따라서 증가하였으며, 이때 아크롤로니트릴과 프로필린의 선택율은 일정하게 유지되었다. 최대의 활성은 Nb₂O₅-V_0.4Mo₁Te_0.1 촉매 중 니오비움산화물이 25wt%가 되었을 때 얻었으며, 니오비움산화물은 프로판의 탈수소과정에 선택적인 촉매임을 알았다.

Conversion of propane to acrylonitrile via ammoxidation was studied using physically mixed catalysts composed of Nb₂O₅(10∼30wt%) and V_0.4Mo₁Te_0.1. Catalytic activities of ammoxidation were improved by adding strong acidic niobium oxide to V_0.4Mo₁Te_0.1, the selectivities to acrylonitrile+propylene being remained constant. The maximum activity was obtained at the mixing ratio 25wt% niobium oxide in Nb₂O₅-V_0.4Mo₁Te_0.1.Niobium oxide was found to be a selective catalvst for the oxidative dehydrogenation of propane.
