标 题:Method of synthesizing materials integrating supernatant recycle
发明人：HODGKINS ROBERT P; KOSEOGLU OMER REFA
权利人:SAUDI ARABIAN OIL CO
摘要:Methods are disclosed for synthesizing materials, including an initial synthesis in the presence of WS-ODSO (which can include a pH-modified WS-ODSO composition, in certain embodiments a neutralized WS-ODSO composition), and one or more subsequent syntheses using supernatant (“mother liquorâ€?) from a previous synthesis of the same or different materials. The synthesized materials in the initial synthesis and in subsequent synthesis can be the same or different inorganic oxide materials including amorphous oxides, crystalline oxides or oxides of metals. The methods advantageously reduce the amount of utility water required for synthesizing a material and reduce the water waste, and reduce the DSO waste from a refinery and discharge into the environment. In certain embodiments the methods reduce the requirements to procure an alkaline reagent required for synthesizing materials. In certain embodiments, supernatant can be recycled over multiple synthesis batches of the same or different type of materia.

摘要:Flame spray pyrolysis can be performed using aqueous solvents for the delivery of metal and/or metalloid oxide precursors while obtaining desirably high flame temperatures for the synthesis of uniform submicron inorganic oxide particles. A multiple liquid channel nozzle can be used to deliver liquid for the formation of the aerosol that is combusted in the flame. One or both channels can deliver liquid with metal/metalloid precursors and/or organic fuels. Flame spray pyrolysis can be used to form metal tungsten oxide submicron particles. Metal tungsten oxide compositions can be used in the formation of transparent electrodes. If the transparent electrodes are formed from polymer inorganic particle composites, the composites can further comprise electrically conductive nanoparticles to improve the electrical conductivity.

标题 :Microwave plasma chemical synthesis of ultrafine powders
发明人：SETHURAM KRUPASHANKARA M; KALYANARAMAN RAJA
权利人:MATERIALS MODIFCIATION INC
摘要:The present invention relates to the production of ultrafine powders using a microwave plasma apparatus and chemical synthesis technique. Microwaves generated by a magnetron ( 1 ) are passed through waveguides ( 2 ) before they arrive at the head of a plasmatron ( 3 ). These high energy microwaves ionize a plasma gas, thus releasing large amounts of energy. The energy thus released is utilized to initiate and sustain chemical reactions between the desired elements being pumped in a spiral pattern into the plasmatron ( 3 ). The reaction products are quenched rapidly in a reactor column ( 4 ) into ultrafine powders.
