What is High-Efficiency Conversion of Methanol to BTX Aromatics Over a Zn-Modified Nanosheet-HZSM-5 Zeolite about?
A Zn-modified nanosheet-HZSM-5 zeolite (Zn-SH-HZSM-5) was prepared and tested as a catalyst in the methanol-toaromatics (MTA) reaction. First, both an effective suppression of C 9+ aromatics formation and a significantly enhanced yield of benzene, toluene, and xylene (BTX) aromatics were achieved by reasonably controlling the reactive pathways in this catalytic reaction system. Further alkylation of BTX aromatics to form C 9+ byproducts was effectively limited by the significantly reduced retention time of BTX molecules in the micropore system, with a significantly shortened diffusion-reaction path. Furthermore, the conversion of methanol to BTX was significantly improved by introducing new surface Zn-Lewis acid sites, achieving a synergistic catalysis with Bronsted acid sites. Second, this catalyst also exhibited strong capabilities both to limit the formation and deposition of large-size coke molecules, thanks to its shortened diffusion-reaction path, and to accommodate carbon, due to the high external surface area and considerable stacking mesopores. As a result, our Zn-SH-HZSM-5 catalyst demonstrated good stability in a 100 h on-stream reaction, providing a BTX yield higher tha
