Zusammenfassung:•Multi-functional redox catalysts for naphtha oxy-cracking with air separation.•Up to 75% olefin yield was achieved along with high (C3= + C4=)/C2= ratios.•The redox catalysts facilitate autothermal olefin production with high productivity.•The acidity of zeolite is the key to tune product distributions. This study reports a highly effective redox catalyst platform, i.e. composites of metal-exchanged ZSM5 and CaMn0.75Fe0.25O3@Na2WO4, for “low temperature” (
