The dynamical cross-talk among time-dependent material, diffusion and reaction at multiple scales.

Caption

zeolite-catalyzed methanol and dimethyl ether conversion is a special heterogeneous catalytic process, which is regulated by the multiscale dynamical cross-talk of diffusion—reaction—material: during the MTO and DTO reactions, due to the confined-organics modification, cavity type SAPO-34 material is dynamically evolved in time with the autocatalytic MTO reaction running from the initiation to decay; the time-dependent material, in turn, creates the catalysis with the dynamical evolution of diffusion and reaction.
