Catalyst for preparing 1,5-pentanediol via hydrogenolysis of tetrahydrofurfuryl alcohol, method and application thereof

The present invention provides a method for preparing 1,5-pentanediol via hydrogenolysis of tetrahydrofurfuryl alcohol. The catalyst used in the method is prepared by supporting a noble metal and a promoter on an organic polymer supporter or an inorganic hybrid material supporter, wherein the supporter is functionalized by a nitrogen-containing ligand. When the catalyst is used in the hydrogenolysis of tetrahydrofurfuryl alcohol to prepare 1,5-pentanediol, a good reaction activity and a high selectivity can be achieved. The promoter and the nitrogen-containing ligand in the supporter are bound to the catalyst through coordination, thereby the loss of the promoter is significantly decreased, and the catalyst has a particularly high stability. The lifetime investigation of the catalyst, which has been reused many times or used continuously for a long term, suggests that the catalyst has no obvious change in performance, thus reducing the overall process production cost.

Aerobic depolymerization of fiber-reinforced composites

A method of aerobic depolymerization of fiber-reinforced polymer (FRP) composites using sustainable reagents and conditions. A cured matrix is digested into soluble monomers and oligomers by catalytic aerobic oxidation. Carbon fibers are removed for re-use, then the remaining material is treated and valuable monomers are isolated. The isolated monomers can be converted back into resin precursors for re-use. The method solves the problem created because the typically irreversible cure reaction impedes recycling and re-use of FRP composites.
