Abstract:
The present disclosure relates to a dehydration catalyst, a method for preparing the same, and a method for preparing an alkene using the same. More particularly, the present invention relates to a dehydration catalyst that is mixed-phase alumina including 1 to 18% by weight of alpha-alumina, 65 to 95% by weight of theta-alumina, and 4 to 34% by weight of delta-alumina, a method for preparing the dehydration catalyst, and a method for preparing an alkene using the dehydration catalyst.
