Abstract EN
The ethanol dehydration to ethylene over alumina catalysts prepared by solvothermal and sol-gel methods was investigated.
Also, a commercial alumina was used for comparison purposes.
The results showed that the catalytic activity depends on the properties of catalyst derived from different preparation methods and reaction temperature.
The alumina synthesized by solvothermal method exhibited the highest activity.
This can be attributed to the higher surface area and larger amount of acid site, especially the ratio of weak/strong acid strength as determined by N2 physisorption and NH3-TPD studies.
The solvothermal-derived catalyst exhibited an excellent performance with complete ethanol conversion and 100% selectivity to ethylene at 350°C in comparison with other ones.
In addition, we further studied the catalytic dehydration of alumina catalyst modified with Fe.
The presence of 10 wt.% Fe decreased both conversion and ethylene selectivity.
However, the acetaldehyde selectivity apparently increased.
It was related to the dehydrogenation pathway that takes place on Fe species.
