Abstract

The present invention is directed to a method of producing a solid fuel which includes providing a bio-oil and thermally curing the bio-oil to form a carbonaceous solid. The present invention is also directed to a method of producing a solid fuel which includes providing a bio-oil; subjecting the bio-oil to an extraction procedure with an aqueous liquid to produce a concentrated pyrolytic sugar-containing extract and a water insoluble raffinate comprising a lignin-derived phenolic oil; and thermally curing the phenolic oil to form a carbonaceous solid.
