Integrated processes for producing fuels and biofertilizers from biomass and products produced

ActiveUS20140345341A1Magnifies overall carbon sequestration potentialMaximize useElectrical coke oven heatingBio-organic fraction processingLiquid fuelBiochar
An IBTL system having a low GHG footprint for converting biomass to liquid fuels in which a biomass feed is converted to liquids by direct liquefaction and the liquids are upgraded to produce premium fuels. Biomass residues from the direct liquefaction, and optionally additional biomass is pyrolyzed to produce structured biochar, hydrogen for the liquefaction and upgrading, and CO2 for conversion to algae, including blue green algae (cyanobacteria) in a photobioreactor (PBR). Produced algae and diazotrophic microorganisms are used to produce a biofertilizer that also contains structured biochar. The structured biochar acts as a nucleation agent for the algae in the PBR, as a absorption agent to absorb inorganics from the biomass feed to direct liquefaction or from the liquids produced thereby, and as a water retention agent in the biofertilizer. The ratio of cyanobacteria to diazotrophic microorganisms in the biofertilizer can be selected to optimize the so as to achieve desired total chemically active carbon and nitrogen contents in the soil for a given crop.
