Angewandte Chemie International Edition, EarlyView.Coking is the central source of deactivation of zeolite catalysts. Using in situ XPS along with complementary methods, we identify differences in the formation kinetics and composition of surface coke on industrially relevant ZSM‐5 catalysts during MTH conversion, demonstrating the strong potential of this technique for studying catalyst deactivation ...

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT The rate of a heterogeneous catalytic process may simultaneously be described by several rate equations. In this case, discrimination between the plausible kinetic models is required. An intrinsic kinetic model of a heterogeneous catalytic process may successively be discriminated by the transition from a reaction rate‐limited regime to an ...
