采用三束技术即高能注射方法对γ-Al_2O_3注Mo或注Mo注N制得Mo/γ-Al_2O_3和Mo-N/γ-Al_2O_3催化剂,研究了催化剂在苯胺气相缩合生产二苯胺过程中的催化性能。与γ-Al_2O_3以及浸渍法制得的Mo/γ-Al_2O_3催化剂的催化性能进行了对比,发现注射法制得的Mo/γ-Al_2O_3、Mo-N/γ-Al_2O_3催化剂催化性能明显提高。
The catalysts of Mo / γ-Al_2O_3 and Mo-N / γ-Al_2O_3 prepared by injecting γ-Al_2O_3 into Mo into Mo-N_2O_3 or Mo_N_γ-Al_2O_3 were prepared by three-beam technology, performance. The catalytic performance of Mo / γ-Al_2O_3 and Mo-N / γ-Al_2O_3 catalysts prepared by injection method was improved compared with that of γ-Al_2O_3 and Mo / γ-Al_2O_3 catalysts prepared by impregnation method.
