Cu-based catalyst supported on complex metal oxide structures having meso- and macropores for preparing 1, 2-propanediol

摘要

The present invention relates to a copper-based catalyst for preparing 1,2-propanediol, wherein copper as an active metal is supported on a complex metal oxide structure having mesopores and macropores at the same time, a method for preparing the copper-based catalyst, and method for selectively preparing 1,2-propanediol from dehydration and hydrogenation of glycerol using the copper-based catalyst.

1. A copper-based catalyst for synthesis of 1,2-propanediol, wherein copper as an active metal is supported on a complex metal oxide structure having meso- and macropores represented by Chemical Formula 1, which has been prepared by coprecipitating Mg6Al2O8 as a metal oxide having mesopores and aluminum- and silicone-based inorganic binders:
Alx—Siy—Mg6Al2O8  [Chemical Formula 1] wherein x or y is the molar ratio of coprecipitated Al or Si per 1 mol of the Mg6Al2O8 as a metal oxide having mesopores, x satisfying 0
