Abstract
Official abstract text for this publication.
The present invention relates to: a catalyst for glycerin dehydration; a preparation method therefor; and an acrolein preparation method using the catalyst. According to one embodiment of the present invention, the catalyst is used in glycerin dehydration so as to exhibit high catalytic activity, a high yield and high acrolein selectivity, and has a characteristic in which carbon is not readily deposited, thereby having a long lifetime compared with that of a conventional catalyst.
First claim
Opening claim text (preview).
The invention claimed is: 1. A catalyst for dehydration of glycerin represented by the following Chemical Formula 1: Zr x A n (H y PO m ) z [Chemical Formula 1] in Chemical Formula 1, A is one or more atoms selected from the group consisting of B, W, V, Ca, K, Mg, Sr, Ag, Ni, Zn, Fe, Sn, and Nb; and x, n, m, y, and z represent ratios of atoms or atom groups, wherein x is 0.1 to 6, n is 0.01 to 8, y is 0.1 to 10, m is 1 to 5, and z is 1 to 12. 2. The…
