Title:
GLYCERIN DEHYDRATION CATALYST, PREPARATION METHOD THEREFOR, AND METHOD FOR PRODUCING ACROLEIN
Document Type and Number:
WIPO Patent Application WO/2015/009032
Kind Code:
A1
Abstract:
The present invention relates to a glycerin dehydration catalyst, a preparation method therefor, and a method for producing acrolein. More specially, the glycerin dehydration catalyst can improve the selectivity of acrolein by minimizing by-product formation in a glycerin dehydration reaction, and can maintain high catalytic activity during the reaction.
