Rapid thermal conversion of biomass
ActiveUS7905990B2Improved rapid thermal conversion processEffective recoveryThermal non-catalytic crackingSolid waste disposalLiquid productHeat carrier
A rapid thermal conversion process for efficiently converting wood, other biomass materials, and other carbonaceous feedstock (including hydrocarbons) into high yields of valuable liquid product, e.g., bio-oil, on a large scale production. Biomass material, e.g., wood, is feed to a conversion system where the biomass material is mixed with an upward stream of hot heat carriers, e.g., sand, that thermally convert the biomass into a hot vapor stream. The hot vapor stream is rapidly quenched with quench media in one or more condensing chambers located downstream of the conversion system. The rapid quenching condenses the vapor stream into liquid product, which is collected from the condensing chambers as a valuable liquid product. The liquid product may itself be used as the quench media.

InactiveUS7947155B1Thermal non-catalytic crackingCombustible gas coke oven heatingVolatilesEngineering
This invention involves pyrolysis of feedstock by introducing carbonaceous feedstock, into a hopper and moving it into a reactor tube enclosed in an oven, generating heat within the oven that is in part transferred to the feedstock, heating it to sufficient temperature to pyrolyze the feedstock into useful volatiles and char. A Venturi system produces a negative pressure directing volatiles into a pyro-gas oven producing heat necessary for pyrolysis and generating useful excess heat. The extruded pyrolysis char has uses including charcoal fuel, soil amendments, and activated charcoal while liquids can be produced for processing into fuels. Excess heat may be used to heat water, steam, and air, may be used in air heating and cooling systems, perform mechanical work with a Stirling engine or generate electricity on the order of 100 kW and higher. The system may be operated in a carbon neutral or even carbon negative manner, allowing sequestration of atmospheric carbon dioxide.

The method includes separating BioOil and its constituents from a gas stream using hot inertial separation to maintain the temperature of said BioOil and its constituents above a temperature at which the thick and / or sticky constituents cause inefficient operation of the equipment but low enough so that they do not undergo rapid degradation. Next the gas velocity is reduced to a temperature sufficiently low to allow droplets in the gas stream to settle out but high enough so that a viscosity of said droplets remains low enough to avoid inefficient operation of the separation equipment. Finally, liquid is condensed out of the gas stream.

The process further includes providing additional heat to coal indirectly by heating the chamber, wherein the heating of coal by the sweep gas and by the indirect heating from the chamber causes condensable volatile components to be released into the sweep gas. The sweep gas is removed from the chamber and treated to remove condensable components of coal.

High energy efficiency biomass conversion process
Improved, fuel-efficient systems are provided for the processing of biomass, such as wood or crop residues, food waste or animal waste in order to selectively obtain torrefied and / or carbonized final products. In general, the processes involve thermally drying incoming biomass using a dryer employing the hot gas output of a fuel-operated burner. Next, the dried product is torrefied in an indirect torrefaction reactor so as to evolve light volatile organic compounds which are used as a gaseous fuel source for the burner. The torrefied product can be recovered, or some or all of the torrefied product may be directed to a carbonization reactor coupled with a reactor burner. Carbonization serves to remove most of the remaining VOCs which are used as a gaseous fuel input to the dryer. In certain instances, portions of the dried biomass are directed to the burners, as an additional source of fuel.
