20130025153 | METHOD AND SYSTEM FOR DRYING BIOMASS - Disclosed herein is a drying method and system for removing water from biomass material. The method comprising the steps of: (a) heating said biomass material with a heating fluid to release water from said biomass by evaporation, wherein the heating fluid has been heated with heat generated by a chiller condenser condensing refrigerant from a gas phase to a liquid phase; (b) recovering heat from said heating fluid that has been in contact with said biomass in step (a), by thermally coupling the heating fluid to the refrigerant in the liquid phase to thereby evaporate the refrigerant to the gas phase. | 01-31-2013 |
20130020188 | METHOD FOR PRODUCING BIOFUEL - The present invention relates to a method for producing biofuel from biomass material, comprising the steps of (a) pyrolysing a first fraction of the biomass material having a pyrolysis temperature that is lower relative to the pyrolysis temperature of a second fraction of the biomass material to thereby produce a primary volatile fraction, and (b) separating the primary volatile fraction from the biomass material before pyrolysing the second fraction, to thereby produce biofuel. | 01-24-2013 |
20120245284 | WATER CURABLE RESIN FORMULATIONS - The present invention relates to a water curable resin formulation comprising: (a) an epoxy resin; (b) an aromatic amine curing agent, wherein the molar ratio of amine functional groups in said curing agent relative to the epoxy functional groups of said epoxy resin is 2:1 or less; and (c) a coupling agent comprising a siloxane group coupled to an epoxy reactive group. | 09-27-2012 |
