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 120°C - 300°C. ZSM-5 supported catalysts were active at temperatures over 260°C, 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 240°C, most probably due to coke formation.
Se estudió la deshidratación catalítica de etanol a etileno en fase gaseosa sobre HMOR (Si/Al = 6.5), HZSM-5 (Si/Al = 29), Cu-HZSM-5 (Si/Al = 98) y Fe-HZSM-5 (Si/Al = 151); a presión atmosférica y en un intervalo de temperaturas entre 120-300°C. Los catalizadores soportados en HZSM-5 fueron activos a temperaturas por encima de 260°C, obteniéndose conversiones superiores al 60%. El etileno fue el producto predominante en la deshidratación. La presencia de cobre en la zeolita HZSM-5 incrementó levemente la actividad catalítica a alta temperatura, mientras que con la adición de hierro la conversión de etanol disminuyó. La zeolita HMOR fue activa a temperaturas menores de 200°C, pero se desactivó rápidamente a 240°C debido a la formación de coque.
