A catalyst support comprising at least 95% silicon carbide, having surface areas of ≤10 m2/g and pore volumes of ≤1 cc/g. A method of producing a catalyst support, the method including mixing SiC particles of 0.1-20 microns, SiO2 and carbonaceous materials to form an extrusion, under inert atmospheres, heating the extrusion at temperatures of greater than 1400° C., and removing residual carbon from the heated support under temperatures below 1000° C. A catalyst on a carrier, comprising a carrier support having at least about 95% SiC, with a silver solution impregnated thereon comprising silver oxide, ethylenediamine, oxalic acid, monoethanolamine and cesium hydroxide. A process for oxidation reactions (e.g., for the production of ethylene oxide, or oxidation reactions using propane or methane), or for endothermic reactions (e.g., dehydrogenation of paraffins, of ethyl benzene, or cracking and hydrocracking hydrocarbons).
A process for selective oxidation of ethane or propane or combinations thereof, the process comprising ethane or propane or combinations thereof over a catalyst support comprising at least 90% SiC and devoid of binding agents and a catalyst when formed, the catalyst support being impregnated with a catalyst solution after formation, the process producing olefines, nitriles, or acids, or combinations thereof.
A process for methane oxidative coupling, the process comprising methane over a catalyst support comprising at least 90% SiC and devoid of binding agents and a catalyst when formed, the catalyst support being impregnated with a catalyst solution after formation, the process producing ethylene, propylene, ethane, propane, or combinations thereof.
A process for an exothermic hydrogenation reaction, the process comprising reacting unsaturated hydrocarbon over a catalyst support comprising at least 90% SiC and devoid of binding agents and a catalyst when formed, the catalyst support being impregnated with a catalyst solution after formation, the process producing light and heavy hydrocarbon hydrogenated products.
A process for selective oxidation of butane, the process comprising butane over a catalyst support comprising at least 90% SiC and devoid of binding agents and a catalyst when formed, the catalyst support being impregnated with a catalyst solution after formation, the process producing olefins, nitriles, or acids, or combinations thereof.
