Abstract
Embodiments of the present invention provide for production and recovery of ethanol or other volatile organic compounds, such as acetic acid, from solid biomass material. One embodiment comprises introducing a biomass material to a compartment of a solventless recovery system, wherein the biomass material contains one or more volatile organic compounds; contacting the biomass material with a superheated vapor stream in the compartment to vaporize at least a portion of an initial liquid content in the biomass material, said superheated vapor stream comprising at least one volatile organic compound; separating a vapor component and a solid component from the heated biomass material, said vapor component comprising at least one volatile organic compound; and retaining at least a portion of the gas component for use as part of the superheated vapor stream.
