摘要： 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.

摘要： The present application discloses low temperature, low pressure methods (LTLP) for upgrading and/or stabilizing bio-oil or a bio-oil fraction. One method comprises providing a bio-oil or bio-oil fraction and hydrogen, which are reacted in the presence of a catalyst at a temperature of less than 150° C. and a pressure of less than 100 bar (absolute) to produce a hydrogenated liquid oil at a carbon yield of over 75%. Another method comprises providing a bio-oil or bio-oil fraction, providing oxygen reducing reaction conditions, and reacting the bio-oil or bio-oil fraction under the oxygen reducing reaction conditions at LTLP to produce an upgraded bio-oil product containing fewer carbonyls than the bio-oil or bio-oil fraction. Yet another method comprises providing a bio-oil or bio-oil fraction and a solution comprising one or more fermentation organisms and a sugar source. The solution and bio-oil or bio-oil fraction are combined to obtain a fermentation mixture, which is incubated at 15° C. to 30° C. for 16 to 72 hours to produce an upgraded bio-oil fermentation product containing fewer carbonyls than the bio-oil or bio-oil fraction.

摘要： The present application relates to an iron impregnated biochar and its use as a fertilizer. The iron impregnated biochar of the present application has a ratio of iron (III) to iron (II) ranging from 5:1 to 10:1. The biochar may be produced by a method including treating the biomass with an iron (II) ion solution, pyrolyzing the iron (II)-treated biomass in an oxidative environment and recovering the biochar product from the pyrolyzed iron (II)-treated biomass.
