METHOD FOR PREPARING CATALYST FOR GLYCERIN DEHYDRATION, AND METHOD FOR PREPARING ACROLEIN

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.

主权项

1. A method for preparing a catalyst for glycerin dehydration, comprising the steps of:
reacting a cerium precursor with a solid acid; and reacting a reaction product of the cerium precursor and the solid acid with a phosphorus precursor.
