Catalytic dehydration of ethanol to ethylene over HMOR HZSM-5 modified with copper and iron

José Luis Agudelo / Consuelo Montes de Correa

Catalytic dehydration of ethanol to ethylene on HMOR (Si/Al = 6.5), HZSM-5 (Si/Al = 29), Cu-HZSM-5 (Si/Al = 98) and Fe-HZSM-5 (Si/Al = 151) was studied at atmospheric pressure and 120oC - 300ºC. ZSM-5 supported catalysts were active at temperatures over 260ºC, achieving more than 60% conversion. Ethylene was predominantly produced as a dehydration product. Incorporating Cu did not significantly improve catalytic activity compared to HZSM-5. H-MOR was very active at low temperatures but deactivated rapidly at 240ºC, most probably due to coke formation.
