Zeolite catalyst method uses microwaves to convert waste cooking oil into useful chemicals
Researchers from Kyushu University have revealed that a zeolite material called Na-ZSM-5 is effective in improving the chemical conversion of biomass into olefins—a precursor chemical that makes everything from plastics to pharmaceuticals—using microwaves.
Publishing their work in Chemical Engineering Journal, the team explains that microwave heating of Na-ZSM-5 could open doors to a more energy-efficient and sustainable chemical industry.
If you want to synthesize complex organic compounds, whether it be plastics, pharmaceuticals, or food additives, you generally need to start with chemical precursors with simple structures. Naturally, finding ways to efficiently and sustainably synthesize precursor chemicals is an extensively researched field.

Advanced nuclear magnetic resonance technique reveals precise structural, dynamical details in zeolites
Zeolites are widely used in many industries, yet their intrinsic catalytic nature is not completely understood, due to the complexity of the hydroxyl-aluminum moieties.
Atomic-scale analysis of local environments for the hydroxyl species is essential for revealing the intrinsic catalytic activity of zeolites and guiding the design of high-performance catalysts. However, many unfavorable factors prohibit the elucidation of their fine structures such as low quantity, meta-stable property, structural similarity, hydrogen-bonding environment, and long-range disordered nature.
Recently, a research team led by Prof. Hou Guangjin and Prof. Chen Kuizhi from the Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Sciences (CAS) unraveled the precise structure of complex hydroxyl groups in zeolites with a comprehensive set of self-developed coupling-edited 1H-17O solid-state nuclear magnetic resonance (NMR) methods. The study was published in the Journal of the American Chemical Society.
