Patent number: 8486161Abstract: The present invention is generally directed to methods for processing lignin-containing biomass so as to render it more amenable to hydroprocessing, wherein such processing typically reduces the level of oxygen in the biomass. Following such processing, the resulting reduced-oxygen lignin-derived product can be hydroprocessed into a biofuel suitable for use as a transportation fuel. Additionally, in some embodiments, such methods can be integrated with one or more other processes, wherein such other processes can be production and/or logistical in nature.Type: GrantFiled: December 16, 2008Date of Patent: July 16, 2013Assignee: Chevron U.S.A.

Patent number: 8241374Abstract: The present invention discloses a fluidized bed system for the single step reforming technology for the production of hydrogen. Single step reforming combines the steam methane reforming, water gas shift, and carbon dioxide removal in a single step process of hydrogen generation. In the present invention, to address the heat transfer and the replenishment issues associated with single step reforming, the sorbent particles are fluidized. This fluidization allows the sorbent particles to be regenerated and consequently allows the optimal operating conditions for single step reforming to be maintained.Type: GrantFiled: December 15, 2006Date of Patent: August 14, 2012Assignee: Texaco Inc.Inventors: Farshad Bavarian, James F. Stevens, Balaji Krishnamurty, Yunquan Liu, Curtis L. Krause, Lixin You, Daniel G. Casey

Patent number: 7384621Abstract: Methods for converting hydrocarbon fuels to hydrogen-rich reformate that incorporate a carbon dioxide fixing mechanism into the initial hydrocarbon conversion process. The mechanism utilizes a carbon dioxide fixing material to remove carbon dioxide from the reformate product stream. The removal of carbon dioxide from the product stream shifts the reforming reaction equilibrium toward higher hydrocarbon conversion with only small amounts of carbon oxides produced. Repeated absorption/desorption of carbon dioxide by the fixing materials tends to decrease the fixing capacity of the materials. Hydration of the carbon dioxide fixing materials between one or more cycles serves to sustain their fixing capacity and to enhance the efficiencies of the reforming and shift reactions occurring in the catalyst bed. Hydration can occur during reactor start-up or shut down, periodically over a number of cycles, and/or upon a monitored change in the reformate composition.Type: GrantFiled: April 19, 2004Date of Patent: June 10, 2008Assignee: Texaco Inc.Inventors: James F. Stevens, Julie M. Cao, Thomas M. Vu
