The deactivation causes have been studied for bifunctional catalysts used in the reforming of dimethyl ether (DME). The kinetic runs have been carried out in a fluidized bed reactor in the 275–325°C range. The bifunctional catalysts have been prepared using CuO-ZnO-Al2O3 (of different formulations) as metallic component, and HZSM-5 zeolites (of different acidity, moderated by desilication) as acid...
