Abstract
A method to make triols and diols is described. The method includes the steps of performing an aqueous-phase hydrodeoxygenation reaction on a feedstock containing a biomass-derived reactant in aqueous solution. The feedstock is contacted with a heterogeneous metal-containing bifunctional catalyst or a combination of two or more heterogeneous metal-containing catalysts that catalyze cleavage of C—C and C—O bonds, for a time, temperature, pressure, and weight hourly space velocity to yield a product mix comprising triols, diols, or combinations thereof.

A method to make triols and diols, the method comprising:
- performing an hydrodeoxygenation reaction on a feedstock comprising:
- (i) a biomass-derived reactant, and
- (ii) hydrogen,
- by contacting the feedstock with a heterogeneous metal-comprising bifunctional catalyst or a combination of two or more heterogeneous metal-comprising catalysts that catalyze cleavage of C—C and C—O bonds, for a temperature, pressure, and weight hourly space velocity to yield a product mix comprising triols, diols, or combinations thereof.
A method to make triols and diols, the method comprising:
- performing an aqueous-phase hydrodeoxygenation reaction on a feedstock comprising:
- (i) a biomass-derived reactant in aqueous solution, and
- (ii) hydrogen in stoichimetric excess for reaction of the biomass-derived reactant to a diol product,
- by contacting the feedstock with a heterogeneous metal-comprising bifunctional catalyst or a combination of two or more heterogeneous metal-comprising catalysts that catalyze cleavage of C—C and C—O bonds,
- at a temperature from about 100° C. to about 500° C., a pressure from about 100 psig to about 1000 psig, and a weight-hourly space velocity from about 0.1 to about 50.0 gram of liquid feedstock per gram of catalyst per hour,
- wherein the catalyst or catalysts comprise a metal selected from the group consisting of Pt, Pd, Ru, Ir, W, Co, Ni, Fe, alloys thereof, mixtures thereof, and combinations thereof,
- wherein the catalyst or catalysts are adhered to a support selected from the group consisting of carbon, a refractory oxide, a phosphate-bonded refractory oxide, and combinations thereof;
- and
- wherein the reaction yields a product mix comprising triols, diols, or combinations thereof.
