| 20090131726 | Method of Making Mixed Metal Oxide Containing Sulfur - The invention relates to a method of making Group 3 and Group 4 mixed metal oxide catalyst suitable for the decomposition of ethers to alkenes and alkanols. In an embodiment, it relates to a method of making a cerium-zirconium mixed metal oxide catalyst. In an embodiment, the catalyst made by the process of the invention is used for the production of isopropanol (IPA) from isopropyl ether (IPE). | 05-21-2009 |
| 20110124927 | SELECTIVE PROCESS FOR CONVERSION OF SYNGAS TO ETHANOL - 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. | 05-26-2011 |
| 20110201850 | METHOD OF MAKING ALKYLENE GLYCOLS - Methods and systems for preparing alkylene glycols are described herein. The methods and systems incorporate the novel use of a high shear device to promote dispersion and solubility of alkylene oxides with water. The high shear device may allow for lower reaction temperatures and pressures and may also reduce reaction time. | 08-18-2011 |
| 20130096352 | PROCESS FOR CONVERTING AN ALKYL TERT-ALKYL ETHER INTO AN ALKANOL AND AN ISO-ALKANE - The invention relates to a process for converting an alkyl tert-alkyl ether into an alkanol and an iso-alkane wherein the alkyl tert-alkyl ether is contacted with a hydrocracking catalyst in the presence of hydrogen under hydrocracking process conditions. | 04-18-2013 |
| 20130178671 | PRODUCTION OF ETHANOL FROM SYNTHESIS GAS - A process for producing ethanol from synthesis gas by reacting the hydrogen and carbon monoxide of the synthesis gas to provide methanol, which then is subjected to dehydration to produce at least one ether, such as dimethyl ether. The ether, such as dimethyl ether, then is subjected to carbonylation with unreacted carbon monoxide from the synthesis gas to provide at least one acetate, such as methyl acetate. The acetate then is subjected to hydrogenolysis to produce ethanol. | 07-11-2013 |
| 20140275642 | EFFICIENCY, FLEXIBILITY, AND PRODUCT VALUE OF A DIRECT ALKANES TO OXYGENATES PROCESS - A method for preparing oxygenated hydrocarbons includes steps of: reacting a first heated hydrocarbon-containing gas stream with an oxygen-containing gas stream in a reactor for form a first product blend, recovering the energy generated in the reactor in order to preheat incoming hydrocarbon feed to the reactor and/or to drive endothermic reactions that generate synthesis gas, separating and condensing one or more liquid oxygenated hydrocarbons from the product stream, separating a reject stream from a recycle stream, mixing remaining gaseous hydrocarbon product from the recycle stream with the first hydrocarbon-containing gas stream after one reaction cycle, converting the first reject stream to a synthesis gas mixture, and converting the synthesis gas mixture to light alkanes to be blended with one or with oxygenates in an output stream to optionally form higher molecular weight oxygenates. | 09-18-2014 |
| 20150329451 | SYNTHESIS OF TETRAHYDROMYRCENOL - The present invention relates to a new and improved synthesis of tetrahydromyrcenol (IUPAC name: 2,6-dimethyl-2-octanol). | 11-19-2015 |
