Publication number: 20090326080Abstract: A process for converting methanol to ethanol which comprises reacting methanol and carbon monoxide in the presence of a catalyst to produce a product comprising at least 25 mole % methyl acetate and, in some instances, acetic acid. The acetic acid then is reacted with at least one alcohol to produce at least one acetate selected from methyl acetate, ethyl acetate, and butyl acetate. The at least one acetate (if produced) and the methyl acetate produced as a result of reacting methanol and carbon monoxide then are hydrogenated to produce ethanol. Syngas may be produced from biomass to produce all or a portion of the methanol, hydrogen, and carbon monoxide requirements for the process.Type: ApplicationFiled: February 20, 2009Publication date: December 31, 2009Inventors: Esteban Chornet, Boris Valsecchi, Yasmin Avila, Betty Nguyen, Jean-Michel Lavoie

Publication number: 20090018371Abstract: Methods and apparatus for producing alcohols from syngas are disclosed herein. In some variations, syngas is catalytically converted to methanol in a first reaction zone, and residual syngas from the first reaction zone is then catalytically converted to ethanol in a second reaction zone. Also, in some variations, syngas is catalytically converted to methanol in high yield in a first reaction zone, and the methanol is then converted (optionally, with additional syngas) to ethanol in a second reaction zone.Type: ApplicationFiled: July 1, 2008Publication date: January 15, 2009Applicant: Range Fuels, Inc.Inventors: Robert E.
