在二氧化碳存在下，丙烷脱氢制丙烯在未助催化和钾助催化的Ga_2O_3催化剂上进行了研究。结果表明，CO2的加入提高了Ga2O3催化剂的初始活性。在0.2 h的反应周期后，丙烷转化率和丙烯选择性分别达到33%和93%，而在氩气存在下，在相同条件下仅实现25%的转化率和90%的选择性。(C)2003 Elsevier B.V.保留所有权利。
The dehydrogenation of propane to propene in the presence of carbon dioxide has been carried out over unpromoted and potassium promoted Ga2O3 catalysts. It was found that carbon dioxide enhance the initial activity of the Ga2O3 catalyst. After 0.2 h of reaction periodic propane conversion and propene selectivity reach 33 and 93%, respectively, while in the presence of argon only 25% conversion and 90% selectivity are achieved under the same condition.
