本文利用非稳态实验方法研究了丙烷在Ｖ－Ｓｂ／Ａ１２Ｏ３催化剂上的氨氧化过程。测定了丙烷的消耗速率、吸附速率和吸附平衡常数。实验发现：丙烷氨氧化制丙烯腈过程的控制步骤是丙烷在催化剂上的表面反应。
In this paper, the ammoxidation of propane over V-Sb / A12O3 catalyst was investigated by means of unsteady experimental method. Propane consumption rate, adsorption rate and adsorption equilibrium constant were determined. The experimental results show that the control step of ammoxidation of propane to acrylonitrile is the surface reaction of propane on the catalyst.
