In-situ formation of [AlO₄]⁰ site for confined catalytic cracking to ethylene with low methane selectivity.

ABSTRACT: Ethylene, one of the major basic chemicals in the modern chemical industry, has been industrially produced mainly through intensive energy-consuming steam cracking processes from light oil fractions or shale gas operated above 800 °C following the radical mechanism and seriously suffering from high methane selectivity. Herein, we report an efficient catalytic cracking reaction of 1-pentene over a tailored ZSM-5 catalyst at 700 °C with a C₂H₄/C₃H₆ ratio of 1.31 and a CH₄ selectivity below 5%, which provides an energy-saving and economically viable route for ethylene production from light oil fractions, seamlessly integrating with the existing industrial catalytic cracking processes. Mechanistic studies unveil an interesting type of zeol
