Abstract

Monolithic microstructured Al-fiber@HZSM-5 core-shell catalysts have been synthesized by directly growing the shell of HZSM-5 with varied SiO₂/Al₂O₃ molar ratio on the core of sinter-locked aluminum microfibers. Such monolithic catalysts are examined in the methanol-to-propylene reaction, and the best microstructured catalyst of HZSM-5 with SiO₂/Al₂O₃ molar ratio of 200 delivers a C₂⁼-C₄⁼ selectivity of 62% (~ 36% to C₃⁼) as well as a single-run lifetime of 160 h under industrial relevant conditions.
