标 题:Methods of making MOFs, systems for synthesizing MOFs, and methods of coating textiles with MOFs
发明人：GIRI GAURAV; HUELSENBECK LUKE
权利人:UNIV VIRGINIA PATENT FOUNDATION
摘要:A method of synthesis of metal organic frameworks (“MOFsâ€?) includes preparing a metal solution by dissolving at least one metal salt in an aqueous solution and buffering the metal solution with a base to achieve a first pH, the metal solution optionally comprising an organic co-solvent, preparing a linker solution by adding at least one organic acid linker and at least one base to an aqueous solution, and mixing the metal solution and the linker solution to produce the MOFs. The at least one organic acid linker has an ability to be protonated or deprotonated in response to a second pH, and the mixture of the metal solution and the linker solution has a third pH value, where the third pH value is greater than a highest pKa of the organic acid linker. The MOFs may be applied to a textile.

摘要:A process is disclosed for the conversion of a hydrocarbonaceous assets into gasoline. The hydrocarbonaceous assets are converted at a first methanol production facility into methanol by processes comprising gasification and methanol synthesis. At least a portion of the methanol is shipped to a second gasoline production facility that is at least 10 miles in distance from the first location. At the second gasoline production facility, at least a portion of the methanol is converted by a MTG process to produce a gasoline and LPG components and steam. At least a portion of the methanol may also be used in a methanol to olefin process to produce olefins and steam. The olefins may be alkylated with olefins to produce alkylates which may mixed with the gasoline. The steam from one or both of the MTG or MTO processes may also be used by processes such as driving pumps to unload the methanol, driving pumps to deliver the gasoline product, driving compressors to liquefy the LPG components, driving generators to produce electricity, heating other substances, to gasifying imported LNG, and combinations thereof.
