A deactivation kinetic equation for the conversion of dimethyl ether (DME) to olefins (DTO process) has been established. The catalyst has been prepared with a HZSM-5 zeolite (SiO2/Al2O3 ratio of 280) agglomerated with boehmite (mesoporous matrix of weak acidity). The experimental data have been obtained in an isothermal fixed bed reactor in a wide range of operating conditions: temperature, 573–673K;...
