Embodiments of the present invention provide for production and recovery of volatile organic compounds and higher hydrocarbons from biomass material. One embodiment comprises contacting a solid component of a biomass material with a digestive solvent to form a digested biomass stream, and at least a portion of the digested biomass is further thermocatalytically treated to generate higher hydrocarbons. 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; retaining at least a portion of the gas component for use as part of the superheated vapor stream.
