Fig. 5: The intracrystalline and surface diffusion behaviors of C4= molecule in H-ZSM-5 zeolites.

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

Fig. 5

Initial uptake rates of butene molecule over H-ZSM-5 zeolites: a Z-cS, b Z-cM, and c Z-cL. d Surface permeability (α/L) and intracrystalline diffusion rates (Dintra/L2) of butene molecule derived by the uptake rates of H-ZSM-5 samples (as presented in Figs. 3a and 4a–c) following Eq. 2. e Correlation of straight channel percent computed in Table 1 with the intracrystalline diffusion rates (Dintra/L2) of butene molecule. The error bars are smaller than the data points in Fig. 5e.
