Abstract
Bimetallic catalysts for the hydrodeoxygenation (HDO) conversion of lignin into useful hydrocarbons are provided. The catalysts are bifunctional bimetallic ruthenium catalysts Ru-M/X+Y comprising a metal M such as iron (Fe), nickel (Ni), copper (Cu) or zinc (Zn), zeolite Y and cation X+ (e.g. H+) associated with zeolite Y.
Claims8
A method of producing at least one hydrocarbon from lignan, comprising
- exposing a reaction mixture comprising lignin to a bimetallic catalyst having of chemical formula Ru-M/XY, where M is a metal, Y is a Y zeolite and X is a cation associated with the Y zeolite, wherein the step of exposing is performed under conditions suitable for hydrodeoxygenation of lignin in the reaction mixture;
- and
- recovering at least one cyclic alkane from the reaction mixture after hydrodeoxygenation of the lignin.
