Fig. 7: The relationships between the intracrystalline diffusivity with the OCC activity losses and the coke depositions.

From: A diffusion anisotropy descriptor links morphology effects of H-ZSM-5 zeolites to their catalytic cracking performance

Fig. 7

a Correlation of C4= conversions and C2-3= yield deactivation rates with the intracrystalline diffusive rates of butene molecules in H-ZSM-5 crystals. The deactivation rates were calculated on the basis of the catalytic performances displayed in Fig. 3a, b. The data between 20 and 50 h were chosen due to the actual deactivation time. b The coke depositions and the micropore blockage degrees after 50 h of OCC reactions. The error bars are smaller than the data points.
