Abstract

A catalyst is provided. The catalyst includes a carrier and a metal Pd. The carrier is represented by a formula: M x Al (1−x) O (3−x)/2 , where M is an alkaline earth metal, and x is between 0.09 and 0.24. The metal Pd is loaded on the carrier. A method for manufacturing the catalyst and a method for manufacturing a hydrogenated bisphenol A or derivatives thereof using the catalyst are also provided.

First claim

The invention claimed is:

1. A method for manufacturing a hydrogenated bisphenol A or derivatives thereof, comprising:
placing a catalyst into a reactor, wherein the catalyst comprises:
a carrier, represented by a formula: M x Al (1−x) O (3−x)/2 , wherein M is an alkaline earth metal, and x is between 0.09 and 0.24; and
a metal Pd, loaded on the carrier;

introducing a solution containing bisphenol A or derivatives thereof into the reactor, and introducing hydrogen into the reactor, wherein the solution containing bisphenol A or derivatives thereof comprises bisphenol A or derivatives thereof and a solvent, wherein the solvent comprises a monohydric alcohol; and
heating the solution containing bisphenol A or derivatives thereof in order to form a hydrogenated bisphenol A or derivatives thereof, wherein a reaction pressure is less than or equal to 70 bar, wherein the derivatives of bisphenol A comprise

2. The method for manufacturing the hydrogenated bisphenol A or derivatives thereof according to claim 1 , wherein the alkaline earth metal comprises Mg or Ca.

3. The method for manufacturing the hydrogenated bisphenol A or derivatives thereof according to claim 1 , wherein the metal Pd is between 0.5 wt % and 3 wt % based on the carrier.

4. The method for manufacturing the hydrogenated bisphenol A or derivatives thereof according to claim 1 , wherein the carrier is in amorphous phase.

5. The method for manufacturing the hydrogenated bisphenol A or derivatives thereof according to claim 1 , wherein the reaction pressure is less than or equal to 30 bar.

6. The method for manufacturing the hydrogenated bisphenol A or derivatives thereof according to claim 1 , wherein the reactor comprises a fixed bed or a trickle bed.

7. The method for manufacturing the hydrogenated bisphenol A or derivatives thereof according to claim 1 , wherein the step of heating the solution containing bisphenol A or derivatives thereof is performed at a temperature at 100° C. to 200° C.
