Zeolite-mediated catalytic cracking of alkanes is pivotal in the petrochemical and refining industry, breaking down heavier hydrocarbon feedstocks into fuels and chemicals. Its relevance also extends to emerging technologies such as biomass and plastic valorization. Zeolite catalysts, with shape selectivity and selective adsorption capabilities, enhance efficiency and sustainability due to their well-defined network of pores, dimensionality, cages/cavities, and channels.

The zeolite-catalyzed methanol-to-aromatics (MTA) process is a promising avenue for industrial decarbonization. This process predominantly utilizes 3-dimensional 10-member ring (10-MR) zeolites like ZSM-5 and ZSM-11, chosen for their confinement effect essential for aromatization. Current research mainly focuses on enhancing selectivity and mitigating catalyst deactivation by modulating zeolites' physicochemical properties.

Article Synopsis
  • - A methanol-based economy aims to tackle energy transition challenges by utilizing a zeolite-catalyzed methanol-to-hydrocarbons (MTH) process to create synthetic fuels and chemicals from renewable sources
  • - Despite its potential, the MTH process has faced obstacles, mainly due to its complex mechanisms that hinder widespread use, particularly in CO-neutral systems
  • - This study bridges knowledge gaps by exploring MTH mechanisms through various advanced techniques, revealing how (Koch-)carbonyl groups enhance specific pathways that significantly influence the production of valuable compounds like benzene, toluene, and xylene (BTX)!

Introducing sustainability into advanced catalytic material design is essential to address growing environmental concerns. Among them, synthesizing inorganic zeolite materials from non-traditional sources (like natural clay) offers several advantages, contributing to sustainability and environmental stewardship. With this objective, we used kaolin to synthesize zeolites with different topologies: SSZ-13 (8-MR with CHA topology), ZSM-5 (10-MR with MFI topology), and Beta (12-MR with BEA topology) (MR: member ring), where a simple and flexible synthetic protocol was adopted without any significant changes.
