The influence of straight pore blockage on the selectivity of methanol to aromatics in nanosized Zn/ZSM-5: an atomic Cs-corrected STEM analysis study

摘要

Here we report the direct atomic scale observation of ZSM-5 pores and the influence of extra-framework Al on methanol to aromatic (MTA). We synthesized a nano sized ZSM-5 catalyst with a short b-axis, and fully opened straight channels. A 98% ultrahigh aromatic selectivity, more than 300 hours long life time and high anti-hydrothermal ability can be achieved in the MTA process.
