A new theoretical and practical framework has been developed through operando study of the zeolite catalytic cracking of low‐density polyethylene (as a model reaction) under reaction conditions. Results show that microporous ZSM‐5 gives rise to less cracking products. Hierarchical ZSM‐5 zeolites are more active cracking catalysts, rendering more C2‐C5 hydrocarbons, with a delayed deactivation due to the secondary porosity. This tool in combination with thermogravimetric analysis provides complementary and valuable information for the study, and design of advanced catalysts.
