文摘
- •
Direct DME synthesis from syngas strongly affected by the zeolite particle sizes.
- •
Influence of zeolite particle sizes more significant than the effect of acidity.
- •
Enhanced diffusion of the reaction intermediates with smaller zeolite particles.
- •
Less deactivation with lower concentration of acid sites on the external surface.
