Publication number: 20100261800Abstract: The present invention relates to a process for the production of ethanol, and optionally methanol, from synthesis gas. In particular the present invention relates to a process for the production of ethanol from a carbonaceous feedstock; wherein the carbonaceous feedstock is first converted to synthesis gas which is then converted to methanol, which is then converted to ethanoic acid, which is then esterified and which is then hydrogenated to produce ethanol in the same alcohol synthesis unit in which the said synthesis gas is converted to methanol.Type: ApplicationFiled: December 12, 2008Publication date: October 14, 2010Inventors: Berian John Daniel, Benjamin Patrick Gracey, John Glenn Sunley

Publication number: 20100152307Abstract: A method of producing an iron catalyst for catalyzing the hydrogenation of carbon monoxide is disclosed. The method comprises using a reduced amount of acid for iron dissolution compared to certain previous methods. The resulting acidic iron mixture is heated without boiling to obtain a nitrate solution having a Fe2+:Fe3+ ratio in the range of about 0.01%:99.99% to about 100%:0% (wt:wt). Iron phases are precipitated at a lower temperature compared to certain previous methods. The recovered catalyst precursor is dried and sized to form particles having a size distribution between 10 microns and 100 microns. In embodiments, the Fe2+:Fe3+ ratio in the nitric acid solution may be in the range of from about 3%:97% to about 30%:70% (wt:wt) and the calcined catalyst may comprise a maghemite:hematite ratio of about 1%:99% to about 70%:30%.Type: ApplicationFiled: February 26, 2010Publication date: June 17, 2010Applicant: RENTECH, INC.Inventors: Belma Demirel, Charles B.

Patent number: 7705059Abstract: The present invention relates to a method of producing methanol from a methane source by oxidizing methane under conditions sufficient to a mixture of methanol and formaldehyde while minimizing the formation of formic acid and carbon dioxide. The oxidation step is followed by treatment step in which formaldehyde is converted into methanol and formic acid which itself can further be converted into methanol via catalytic hydrogenation of intermediately formed methyl formate.Type: GrantFiled: April 12, 2006Date of Patent: April 27, 2010Assignee: University of Southern CaliforniaInventors: George A.

Patent number: 7683099Abstract: The invention relates to a method for carrying out heterogeneous catalytic exothermic gas phase reactions at a high temperature and high pressure, during which the synthesis gas comprised of a mixture of make-up gas and/or of recycle gas is fed through at least two synthesis stages that are connected in-series to form a synthesis system. The product gases from the synthesis stages, with the exception of the last stage, are separated into at least two partial flows. One partial flow is cooled until the product is condensated out, and the condensate containing the product is separated from the gaseous constituents. Afterwards, the gaseous constituents are combined with the warm portion of the product gas in order to reach the inlet temperature of the next synthesis stage. In addition, the partial flow from which the product was condensated out and removed, can be heated before being remixed with the warm portion of the product gas.Type: GrantFiled: May 28, 2005Date of Patent: March 23, 2010Assignee: Ammonia Casale S.A.Inventor: Anton Josef Hipp

Patent number: 7579383Abstract: This invention is directed to a process for making a methanol product from a synthesis gas (syngas) feed using a fluid bed reactor. Internal reactor heat transfer is balanced between feed preheat and catalyst bed temperature using appropriate backmixing of feed and catalyst.
