The present disclosure relates to an apparatus for generating glycol and a method thereof. More particularly, the present disclosure relates to an apparatus for generating glycol including (a) an aldol reactor; (b) an extractor for extracting an aldol product, unsaturated aldehyde, using an organic solvent that is not mixed with water; (c) a distillation column for removing a raw material from a solution extract that is discharged from the extractor; (d) a hydrogenation reactor for hydrogenating a solution extract that is discharged from the distillation column; and (e) a divided-wall distillation column for isolating glycol from a hydrogenated solution product that is discharged from the hydrogenation reactor, wherein the hydrogenation reactor is a fixed-bed catalytic reactor that is filled with a copper-based catalyst, and a method of preparing the same.

In accordance with the present disclosure, an economical apparatus for preparing glycol which reduces loss of a raw material and provides a high glycol yield while inhibiting generation of by-products, and a method of preparing the same are provided.

Surface hydroxyl groups on porous and nonporous metal oxides, such as silica gel and alumina, were metalated with catalyst precursors, such as complexes of earth abundant metals (e.g., Fe, Co, Cr, Ni, Cu, Mn and Mg). The metalated metal oxide catalysts provide a versatile family of recyclable and reusable single-site solid catalysts for catalyzing a variety of organic transformations. The catalysts can also be integrated into a flow reactor or a supercritical fluid reactor.
