Mechanical properties of ZSM-5 extruded catalysts: calcination process optimization using response surface methodology

The mathematical models based on response surface methodology were developed to study the effects of calcination process factors on the mean strength and Weibull modulus of ZSM-5 extruded catalysts. The response surfaces analyses show that the mean strength increases as calcination temperature increases, and the Weibull modulus increases first and then decreases, reaching a peak at 600 °C. The mean strength increases with increasing calcination...
