| Figure 3 shows by, Cu / ZSM-5 there are three oxygen desorption peaks, according to literature [1], these three peaks correspond to the weak chemisorption of molecular sieve oxygen desorption (383 K), adsorbed on ZSM -- 5, aluminum bits on the oxygen desorption (573 K) and adsorption in the catalyst of copper ions on the oxygen desorption (700 K), of which 700 K desorption peak intensity and area of the largest shows that copper ions are the main oxygen adsorption sites. |
