| titleOfInvention | Method for improving quality of biomass-based polyol through hydrogenation |
| abstract | The invention discloses a method for improving the quality of biomass-based polyol through hydrogenation, which comprises the following steps: uniformly mixing biomass-based polyol obtained by liquefying lignocellulose biomass, a supported amorphous alloy catalyst and a solvent, replacing air in a reaction container by using nitrogen, filling hydrogen to the pressure of 0.5-5.0 MPa, heating to 80-180 ℃, and reacting for 0.5-10 h to obtain the biomass-based polyol subjected to hydrogenation upgrading. The invention aims at the hydrogenation and quality improvement of the biomass-based polyol obtained by liquefying the lignocellulose biomass, can effectively adjust the hydroxyl value of the biomass-based polyol, lightens the color of the biomass-based polyol, stabilizes the hydroxyl compound in the hydrogenation process, has higher removal rate of the carbonyl compound, and is beneficial to improving the quality of downstream polyurethane foam products. |
