Patent number: 9624436Abstract: 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.Type: GrantFiled: May 16, 2013Date of Patent: April 18, 2017Assignee: SHELL OIL COMPANYInventors: Phillip Guy Hamilton, Corey William Radtke, Keith Michael Kreitman, Paul Richard Weider, Robert Lawrence Blackbourn

Publication number: 20130309356Abstract: In one embodiment, the animal feed product of the present invention is devolatilized. In addition, in various embodiments, the animal feed of the present invention is already size-reduced, which allows ease of handling and transport, such as further densification, including pelletization and/or other formatting process for rail transportation. In various embodiments, the animal feed of the present invention has a low sulfur content, high amount of ADF, and/or high amount of starch to meet desired nutritional amounts, which further can allow it to be a substantial or complete replacement of forage. In addition, in certain embodiments, grain is preferably not used in the production of the animal feed, but rather vegetative material is used instead.Type: ApplicationFiled: May 16, 2013Publication date: November 21, 2013Inventors: Corey William RADTKE, Phillip Guy Hamilton, Keith Michael Kreitman
