摘要: An object of the present invention is to provide a catalyst for glycerin dehydration reaction producing unsaturated aldehyde and carboxylic acid at higher yield by glycerin, that can reduce decrease in time conversion ratio yields acid. Another produce acrolein acrylic has longer life. Still another method preparing catalysts above. A comprising carrier, wherein carrier includes least one metal oxide selected from group consisting TiO 2 , SiO Al O 3 ZrO Nb 5 bimodal porous structure which volume between pore mesopores having size more than nm less 50 macropores or equal 0.5, configures support W-containing thereon containing element P, Si, Mo, V, addition thereon, cause catalytic dehydrogenation with
