摘要:The invention relates to a process for the synthesis of sulfonylmethanes and derivatives thereof of the formula M[(RSO 2 ) 2 CH] m (I), in which M represents H, an alkali metal or alkaline earth metal or NR' 4 , R' and R are monovalent organic radicals and m represents the valence of M. n The process comprises reacting an ionic carbide with a sulfonyl halide, hydrolyzing the product obtained, adding a compound M y Y m , in which Y represents an anion capable of reacting with the cation of the ionic carbide to the reaction medium before or after hydrolysis to give a compound which can be separated from compound (I), and y represents the valence of Y.

摘要:Solid reaction products with a dense nanocrystalline structure are formed from reactant particles with diameters in the nano-scale range by compacting the particles into a green body, then passing an electric current through the body causing Joule heating sufficient to initiate the reaction to form the reaction product while simultaneously applying pressure to the reacting body to density it to a density approaching the theoretical density of the pure product. Surprisingly, this process results in a reaction product that retains the nanocrystalline structure of the starting materials, despite the fact that a reaction has occurred and the materials have been subjected to highly stringent conditions of electric current, heat and pressure.

标 题 :Process for converting a metal carbide to diamond by etching in halogens
发明人：MCNALLAN MICHAEL J; ERSOY DANIEL; GOGOTSI YURY; WELZ SASCHA
摘要:A process for the synthesis of carbon coatings on the surface of metal carbides, preferably SiC, by etching in a halogen-containing gaseous etchant, and optionally hydrogen gas, leading to the formation of a carbon layer on the metal carbide. The reaction is performed in gas mixtures containing 0 to two moles of hydrogen for every two moles of halogen gas, preferably about 0.5 to one mole of hydrogen gas for eery two moles of halogen gas, at temperatures from about 100° C. to about 4,000° C., preferably about 800° C. to about 1,000° C., over any time range, maintaining a pressure of preferably about one atmosphere.

摘要:A process for the synthesis of carbon coatings on the surface of metal carbides, preferably SiC, by etching in a halogen-containing gaseous etchant, and optionally hydrogen gas, leading to (he formation of a carbon layer on the metal carbide. The reaction is performed in gas mixtures containing about 0% (trace) amounts to 100% halogen-containing gaseous etchant, e.g., Cl 2 , and about 0% to 99.9% H 2 (hydrogen gas) at temperatures from about 100° C. to about 4,000° C., preferably about 800° C. to about 1,200° C., over any time range, maintaining a pressure of preferably about one atmosphere, to about 100 atmospheres.

标题:Permreactor and separator type fuel processors for production of hydrogen and hydrogen, carbon oxides mixtures

摘要:Overall permreactor-separator process designs and effective permreactor designs with increased mass and heat transfer, reactant conversion, product yield and optional recycling for processing methane, hydrocarbons, alcohols, carbon monoxide, natural gas, acidic natural gas, cool gas, biomass gas, and mixtures of hydrocarbons with carbon dioxide, based on the reforming reactions of these feedstocks with steam and carbon dioxide and the dehydrogenation reactions of saturated hydrocarbons. Final exit streams from these gas phase processors contain pure hydrogen, hydrogen and carbon monoxide mixture, hydrogen and carbon dioxide mixture, and can be used as a direct feed in molten carbonate, solid oxide, proton exchange membrane, alkaline, phosphoric acid and other types of hydrogen driven fuel cells. Same final exit processed streams can be alternatively used for direct chemical synthesis such as methanol, for hydrogenations and hydrogen based reduction reactions such as those of unsaturated hydrocarbons to paraffins, and as feed in power generation systems such as gas turbines and gas engines.
