Proximity-guided control of framework Al pairs in ZSM-5 for enhancing hydride transfer and aromatics formation in propane–DME co-aromatization

Key Points

• The aim is to investigate how high-concentration Al pairs in ZSM-5 affect hydride transfer and aromatics production during propane-DME co-aromatization.
• Analyzed zeolites with varying concentrations of Al pairs
• Examined conversion rates of propane and DME
• Measured selectivity towards aromatics
• High-concentration Al pairs significantly improved propane conversion rates
• Aromatics selectivity was notably increased
• Hydride transfer efficiency was enhanced with optimized Al pair proximity
