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.

Methods and systems for processing biomass material

Embodiments of the present invention provide for efficient and economical production and recovery of ethanol or other volatile organic compounds, such as acetic acid, from solid biomass material, particularly on a larger scale, such as on the commercialization or industrial scale. According to one aspect of the invention, the method comprises (a) generating at least about 10 tons of prepared biomass material by adding a microbe, optionally an acid, and optionally, an enzyme to a solid biomass; (b) storing the prepared biomass material for at least about 24 hours in a storage facility to allow production of at least one volatile organic compound from at least a portion of the sugar in the solid biomass; and (c) capturing the at least one volatile organic compound by using a solventless recovery system.

Process for producing volatile organic compounds from biomass material

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 vapor component for use as part of the superheated vapor stream.

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.

Disclosed is an integrated process for producing 2,6-naphthalene dicarboxylicacid comprising oxidizing a methylnaphthalene feedstock, hydrodebrominating the crude naphthoic acid product under conditions different from any work known in the art, forming a potassium salt of the acid; disproportionating the potassium salt to produce 2,6 potassium salts of NDA; selectively precipitating K NDA; selectively precipitating the monopotassium salt of 2,6 NDA(KHNDA); disproportionating the KHNDA into 2,6 NDA and K2NDA; further reacting the 2,6 NDA in a pipe reactor; and drying the product 2,6 NDA by conventional means or directly slurrying directly into a PEN process. The process can tolerate impurities in the economical methylnaphthalene feed and the resulting 2,6 NDA is of high quality with <50 ppm potassium.
