Process for the selective production of propanols by hydrogenation of glycerol |
| 摘要 |
The present invention discloses a process for the selective hydrogenation of glycerol in the liquid phase to produce 1- and 2-propanols in high yields as the major organic products. The process comprises subjecting a glycerol stream having at least 30% by weight water to a combination of low pressure and high temperature hydrogenation conditions in the presence of a promoted or un-promoted skeletal copper catalyst. |

1. A catalytic process for the hydrogenation of glycerol comprising
a) obtaining a glycerol-containing stream having a water content of at least 30% by weight of the total glycerol containing stream; b) subjecting the glycerol-containing stream to hydrogenation in the liquid phase in a reactor in the presence of a skeletal copper catalyst at a reaction temperature of greater than 250° C., and a reaction pressure of less than 100 bar; and c) wherein a combined weight % yield of 1-propanol and 2-probanol of at least 15% based on the total weight of glycerol feed is obtained as a major product. |
