摘要:
The present invention relates to a method for preparing a catalyst for glycerin dehydration, a catalyst for glycerin dehydration prepared thereby, and a method for preparing acrolein. More particularly, the catalyst for glycerin dehydration prepared by the preparation method is able to minimize by-product formation to improve acrolein selectivity and to maintain high catalytic activity during the reaction.
