20090018374 | HYDROGENATION CATALYST AND USE THEREOF FOR HYDROGENATING FISCHER-TROPSCH ENDPRODUCTS - A hydrogenation catalyst particularly suitable for hydrogenating oxygenates in a hydrogenation unit of a Fischer-Tropsch plant is disclosed. A preferred embodiment comprises more than 5% and less than 20% nickel based on a wide pore alumina support. The catalyst successfully hydrogenates oxygenates which otherwise tend to poison a catalyst in a hydroconversion unit downstream. Moreover, the temperature at which the unwanted hydrogenolysis of long chain paraffins to methane occurs is higher for one catalyst disclosed herein than a comparable known catalyst. This allows the hydrogenation plant to operate at a higher temperature. | 01-15-2009 |
20100280290 | "METHOD OF MAKING M41S FAMILY MOLECULAR SIEVE" - This disclosure relates to a novel method of making and recovering M41S family molecular sieve materials using synthesis mixtures having high solids-content and without a purification step. The solids-content, for example, is in a range from about 20 wt. % to 50 wt. %. The method also includes the step of mixing at least a portion of the M41S made with another material to form a composition, wherein the amount of said material to be mixed with said M41S product is such that said composition having less than 10 wt. % free fluid. The material mixed with the M41S made includes metal oxides, metal nitrides, metal carbides and mixtures thereof, as well as absorptive material capable of absorbing mother liquor and selected from the group consisting of carbon silica, alumina, titania, zirconia and mixtures thereof. The amount of the wastewater generated by this novel method is reduced by at least 50% to as much as 100% as comparing with conventional method of making M41S materials. By reducing and/or eliminating at least a portion of the wastewater generated in the synthesis product, the new method reduces cost of making of M41S materials and provides a more environmentally-friendly synthesis product. | 11-04-2010 |
20110263912 | Control Of Kinetic Decomposition In Mixed Conducting Ion Transport Membranes - Mixed conducting ion transport membrane comprising a multi-component metallic oxide compound represented by the formula Ln | 10-27-2011 |
20110275866 | Feed Gas Contaminant Removal in Ion Transport Membrane Systems - An oxygen ion transport membrane process wherein a heated oxygen-containing gas having one or more contaminants is contacted with a reactive solid material to remove the one or more contaminants. The reactive solid material is provided as a deposit on a support. The one or more contaminant compounds in the heated oxygen-containing gas react with the reactive solid material. The contaminant-depleted oxygen-containing gas is contacted with a membrane, and oxygen is transported through the membrane to provide transported oxygen. | 11-10-2011 |
20120149950 | PLANT FOR THE HOMOGENEOUS OXIDATION OF METHANE-CONTAINING GAS AND PROCESS FOR THE OXIDATION OF METHANE-CONTAINING GAS - The invention relates to the process for homogenous oxidation of methane-containing gas comprising feeding of methane-containing gas preheated to 430-450° C. to at least three sequentially installed oxidation reactors, wherein each reactor, with the exception of the last one, is independently connected to waste-heat boilers, the reactors are fed with oxygen for oxidation of methane-containing gas, wherein the gas mixture temperature is increased to 540-560° C. with subsequent rapid quenching-cooling of the gas mixture to 440-450° C. in waste-heat boilers where steam is formed which is fed to a rectification tower for separation of end products, from the last reactor the reaction mixture is fed to a separator, from the separator the liquid phase is fed to the rectification stage where rectified methanol, ethanol and formaldehyde are produced, and the gas phase is fed for cleaning it of SO2, CO and CO2, and in the process, partial purging of the circulation cycle is performed to remove inert gases, and after cleaning and purging the cycle is completed by replenishing the gas-phase/cycled gas with the original methane-containing gas and re-feeding, the resulting gas to the reactor. The invention makes it possible to increase efficiency, increase product yield and improve the environmental situation. | 06-14-2012 |
20120323053 | Methods for biomass Deconstruction and Purification - The present invention provides processes for deconstructing and purifying biomass using water. The method includes the steps of loading a reactor with biomass and water, establishing and maintaining a deconstruction temperature and pressure for a deconstruction period, flushing the reactor with water, and repeating these steps to produce a solid phase and a biomass hydrolysate. | 12-20-2012 |
20130023702 | Serial Deconstruction of Biomass - The present invention provides processes for deconstructing biomass using water. The method generally includes loading a reactor with biomass and water, heating the reactor to a first deconstruction temperature and establishing a first deconstruction pressure, maintaining the reactor at the first deconstruction temperature and a first deconstruction pressure for a first deconstruction period, flushing the reactor with water, and repeating these steps one or more times after establishing a second deconstructing temperature and second deconstruction pressure. | 01-24-2013 |
