Abstract

In this communication, a new theoretical and practical framework through Operando Catalysis to study the zeolite catalytic cracking of the low‐density polyethylene as model reaction, under reaction conditions is provided. Results show that a microporous ZSM‐5 gives rise to less cracking products. Hierarchical ZSM‐5 zeolites are more cracking active, 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.
