Synthesis of monolithic Al-fiber@HZSM-5 core-shell catalysts for methanol-to-propylene reaction
Monolithic microstructured Al-fiber@HZSM-5 core-shell catalysts have been synthesized by direct in-situ growing the shell of HZSM-5 with varied SiO 2 /Al 2 O 3 molar ratio on the core of sinter-locked aluminum microfibers. Such monolithic catalysts are employed in methanol-to-propylene reaction, and the best catalyst with SiO 2 /Al 2 O 3 molar ratio of 200 delivers a C 2 = -C 4 = selectivity of 62% (~36% to C 3 = ) as well as a single-run lifetime of 160 h under industrial relevant conditions.doi:10.1016/j.catcom.2015.09.026 fatcat:fhek6yow3jbb3f7g5cmxnkubom
