Abstract
Embodiments of the present invention provide for efficient and economical production and recovery of ethanol or other volatile organic compounds. One embodiment comprises contacting a solid component of a biomass material with a solution adapted to facilitate saccharification. The solid component is generated by a method comprising: 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; separating a vapor component and a solid component from the heated biomass material; and retaining at least a portion of the gas component for use as part of the superheated vapor stream. In one embodiment, the solid component contacted with the solution is further subjected to enzymatic hydrolysis and/or fermentation.
