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.

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.

A process for treating agglomerating coal includes providing dried, pulverized, agglomerating coal, and treating the coal in a vessel with a gas stream having an oxygen content sufficient to form at least some oxides on surface of coal particles, wherein the oxides are sufficient to convert coal into substantially non-agglomerating coal. The treated coal is transferred into a pyrolyzing chamber and passed into contact with an oxygen deficient sweep gas, the sweep gas being at a higher temperature than the temperature of the coal so that heat is supplied to the coal. 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.
