Abstract:
The present disclosure relates to a catalyst for dehydration of glycerin, a preparation method thereof, and a production method of acrolein using the catalyst. Particularly, the catalyst according to an embodiment of the present disclosure is used in a dehydration reaction of glycerin to exhibit high catalytic activity, a high yield, and high selectivity to acrolein and acrylic acid, and has a longer lifetime compared to the conventional catalysts due to a characteristic that coke carbon cannot be easily deposited on the surface of the catalyst.

Claim (Index 4):
A preparation method of a catalyst for dehydration of glycerin, comprising the step of mixing one or more precursors selected from the group consisting of precursors of V, Fe, Nb, and Zn, a zirconium precursor, a phosphorus precursor, and a tungsten precursor, followed by drying and calcining to produce a catalyst represented by the following Chemical Formula 1:\n Zr a (M 1 ) b (M 2 ) c W d P e H x O y \u2003\u2003[Chemical Formula 1] wherein, in Chemical Formula 1, M 1  and M 2  are the same as or different from each other, and are independently V, Fe, Nb, Zn, or a combination thereof; a, b, c, d, and e represent ratios of atoms, wherein a is 0.1 to 6, b/a is 0 to 1, c/a is 0 to 1, d/a is 0 to 1, and e/a is 0 to 10, provided that at least one of b and c is not 0; and x and y are values determined according to a bonding state of crystallization water, and are independently 0 to 10.
