Multiscale reaction and deactivation model of MTO and DTO reactions over SAPO-34, from the catalyst-bed scale to the catalyst-crystal and CHA-cavity scale. (IMAGE)
Caption
Originating from reactant shape-selectivity of zeolite materials (the mass transfer of DME is constrained relative to methanol), even it is performed in the same zeolite material and possessing very close hydrocarbon pool mechanisms, the dynamical proceeding of the DTO reaction (relative to MTO) is distinctly regulated by the cross-talk of diffusion-reaction-material.
