  • Membrane electro-catalytic system and process for obtaining fuel gas
    Patent number: 8992760
    Abstract: An electro-catalytic membrane system for preparing fuel gas from water operates at normal levels of pressure and temperature. The system includes a high frequency power source, a power supply system, a programmable control unit, an electro-catalytic membrane module, and a module for processing the fuel gas. The electro-catalytic membrane module includes metallic electrodes in a concentric arrangement. The space between the concentric electrodes includes granular carbon and metallic particles. A fixed membrane is arranged at a lower end of the space while a mobile membrane is arranged at an upper end of the space. The electro-catalytic membrane module is further provided with sensors for measuring process parameters, conduits, and valves for supplying and removing liquids. A system for cooling the metallic electrodes is also provided.

  • Use of functionalized mesoporous silicates to esterify fatty acids and transesterify oils
    Publication number: 20050107624
    Abstract: The present invention provides a method to prepare a fatty acid lower alkyl esters from a feedstock, such as a vegetable or an animal oil, comprising one or more fatty acid glycerol esters such as mono-, di- or tri-glycerides, and free fatty acids, comprising combining the feedstock, a lower alcohol and an acidic mesoporous silicate under conditions wherein the mesoporous silicate catalyzes the formation of the corresponding fatty acid lower alkyl ester of the free fatty acids an optionally glycerol.
