20080282882 | GAS SEPARATION MEMBRANE COMPRISING A SUBSTRATE WITH A LAYER OF COATED INORGANIC OXIDE PARTICLES AND AN OVERLAYER OF A GAS-SELECTIVE MATERIAL, AND ITS MANUFACTURE AND USE - A gas separation membrane and a method of manufacturing such gas separation membrane that comprises a porous substrate treated with a layer of metal-coated inorganic oxide particles and with the layer of such metal-coated inorganic oxide particles being coated with an overlayer of a gas-selective material. | 11-20-2008 |
20090120287 | GAS SEPARATION MEMBRANE SYSTEM AND A METHOD OF PREPARING OR RECONDITIONING AND THE USE THEREOF - A gas separation membrane system and a method of preparing such gas separation membrane system by providing a porous support upon which is supported a membrane layer comprising a first gas-selective material and having a membrane thickness and removing therefrom a substantial portion of the first gas-selective material from the membrane layer by the use of an ultra-fine abrasive to thereby provide the membrane layer having a reduced membrane thickness. A second gas-selective material is deposited upon the membrane layer having the reduced membrane thickness to provide an overlayer of the second gas-selective material having an overlayer thickness so as to thereby provide the gas separation membrane system having the membrane layer of the reduced membrane thickness and the overlayer of the overlayer thickness. | 05-14-2009 |

20150094503 | CATALYST FOR PRODUCING HYDROCARBONS - A hydropyrolysis catalyst and a process using that catalyst are described. The catalyst comprises a support and an active metal component wherein the catalyst is an eggshell type catalyst having the active metal component located in the outer portion of the support. | 04-02-2015 |
20150133704 | PROCESS FOR PRODUCING HYDROCARBONS - A process for converting biomass to products is described. Biomass is contacted with hydrogen in the presence of a fluidized bed of hydropyrolysis catalyst in a reactor vessel under hydropyrolysis conditions; and products and char are removed from the reactor vessel. The products leave the fluidized bed at an exit bed velocity, the char has a settling velocity that is less than the exit bed velocity and hydropyrolysis catalyst has a settling velocity that is greater than the exit bed velocity. | 05-14-2015 |
