Catalytic conversion of glycerol to bio-based aromatics using H-ZSM-5 in combination with various binders

The use of H-ZSM-5 with various binders (Al 2 O 3 , SiO and kaolinite, 10 wt% on catalyst formulation) for the catalytic conversion glycerol to bio-based aromatics (GTA) was investigated in a continuous bench-scale unit at pyrolysis temperature 450 °C, upgrading 500 WHSV pure 1 h ?1 atmospheric pressure, their performance compared (SiO /Al molar ratio 28). latter gave peak BTX carbon yield ca. 31.1C.%, life-time 220 min, total productivity 312 mg g H-ZSM-5. introduction affects performance, which is most profound promising H-ZSM-5/Al catalyst. It shows prolonged 320 min higher 518 H-ZSM-5, without binder. Catalyst characterization studies show that addition binder does not have major effect specific surface area, pore volume, acidity. Other relevant properties were affected, though, such as micropore volume ), reduced Brønsted acidity crystallinity ). Coke formation causes severe deactivation, ultimately leading an inactive formation. after oxidative regeneration showed textural regenerated catalysts close those original catalysts. However, some dealumination occurs, resulting decreased acidity, causing irreversible needs attention future development studies. • H-ZSM-5-in combination three studied (BTX). Best results obtained Al . lifetime 66% obtained. this due coke accommodation capacity.
