Publication number: 20240123401Abstract: The invention present provides a method (and suitable apparatus) to convert biomass to ethanol, comprising gasifying the biomass to produce raw syngas; feeding the raw syngas to an acid-gas removal unit to remove at least some CO2 and produce a conditioned syngas stream; feeding the conditioned syngas stream to a fermentor to biologically convert the syngas to ethanol; capturing a tail gas from an exit of the fermentor, wherein the tail gas comprises at least CO2 and unconverted CO or H2; and recycling a first portion of the tail gas to the fermentor and/or a second portion of the tail gas to the acid-gas removal unit. This invention allows for increased syngas conversion to ethanol, improved process efficiency, and better overall biorefinery economics for conversion of biomass to ethanol.Type: ApplicationFiled: December 27, 2023Publication date: April 18, 2024Inventors: John D. WINTER, Jerrod HOHMAN

Patent number: 8288594Abstract: The present invention provides processes for selectively producing ethanol from syngas. In some variations, the process comprises converting biomass-derived syngas to dimethyl ether, carbonylating the dimethyl ether to methyl acetate, hydrogenating the methyl acetate to methanol and ethanol, and recovering the ethanol product. The methanol is preferably recycled by converting to hydrogen and carbon monoxide for introduction back into the process at distinct points. In certain variations of this invention, fresh syngas feed is introduced downstream of the first unit operation in the sequence. High yields of ethanol from biomass can be achieved according to the disclosed processes.Type: GrantFiled: November 22, 2010Date of Patent: October 16, 2012Assignee: Albemarle CorporationInventors: Ronald C. Stites, Shakeel Tirmizi, Jerrod Hohman, Stephen Deutch

Patent number: 7884253Abstract: The invention provides methods and apparatus for selectively producing ethanol from syngas. As disclosed herein, syngas derived from cellulosic biomass (or other sources) can be catalytically converted into methanol, which in turn can be catalytically converted into acetic acid or acetates. Finally, the acetic acid or acetates can be reduced to ethanol according to several variations. In some embodiments, yields of ethanol from biomass can exceed 100 gallons per dry ton of biomass.Type: GrantFiled: August 25, 2009Date of Patent: February 8, 2011Assignee: Range Fuels, Inc.Inventors: Ronald C.

Publication number: 20090093555Abstract: This invention features methods and apparatus for producing syngas from any carbon-containing feed material. In some embodiments, a substoichiometric amount of oxygen is used to enhance the formation of syngas. In various embodiments, a catalyst is derived from the ash content of the feed material, and this catalyst is used to enhance syngas formation. The syngas can be converted to alcohols, such as ethanol, or to other products.Type: ApplicationFiled: December 16, 2008Publication date: April 9, 2009Applicant: Range Fuels, Inc.Inventors: Ronald C.

In some embodiments, a substoichiometric amount of oxygen is used to enhance the formation of syngas. In various embodiments, both oxygen and steam are added during the conversion of the feed material into syngas. Some variations employ eductors for facilitating flow of solid and gas phases in the processes of the invention. The syngas can be converted to alcohols, such as ethanol, or to other products.Type: ApplicationFiled: July 1, 2008Publication date: January 15, 2009Applicant: Range Fuels, Inc.Inventors: Robert E.
