Abstract: 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.

Abstract: The present invention relates to a method of fractionating bio-oil vapors which involves providing bio-oil vapors comprising bio-oil constituents. The bio-oil vapors are cooled in a first stage which comprises a condenser having passages for the bio-oil separated by a heat conducting wall from passages for a coolant. The coolant in the condenser of the first stage is maintained at a substantially constant temperature, set at a temperature in the range of 75 to 100° C., to condense a first liquid fraction of liquefied bio-oil constituents in the condenser of the first stage. The first liquid fraction of liquified bio-oil constituents from the condenser in the first stage is collected. Also disclosed are steps for subsequently recovering further liquid fractions of liquefied bio-oil constituents. Particular compositions of bio-oil condensation products are also described.

Abstract: The present invention is directed to a pyrolysis method. The method involves providing a biomass and subjecting the biomass, in a reactor operating under conditions of parasitic heat loss of less than 1% of the biomass' chemical energy content, to partial oxidation where, during steady state operation of the reactor, oxygen is provided to the reactor in sufficient quantity to achieve an equivalence ratio of 0.06 to 0.15 to release sufficient energy to support endothermic pyrolysis reactions and produce condensable organic compounds as the major portion of the pyrolysis products.
