摘要: This invention relates to development of novel Cu-based nanocatalysts synthesized via one-pot solution combustion synthesis for CO2 hydrogenation to methanol. The novel Cu-based catalyst has exceptional activity for CO2 hydrogenation with high methanol selectivity in the reaction temperature range between 250° C.-350° C. The novel catalyst also exhibits excellent resilience to deactivation due to sintering.

摘要: A method of producing a syngas composition includes hydrolyzing a metal halide salt to form a hydrohalic acid and a hydroxide salt of the metal in the metal halide salt. The metal includes an alkaline earth metal or an alkali metal. The method includes reacting the hydrohalic acid with a metal carbonate salt, wherein the metal carbonate salt is a carbonate salt of the alkaline earth metal or alkali metal, to form CO2 and the metal halide salt. At least some of the metal halide salt formed from the reacting of the hydrohalic acid with the metal carbonate salt is recycled as at least some of the metal halide salt in the hydrolyzing of the metal halide salt to form the hydrohalic acid and the hydroxide salt. The method also includes electrolytically converting the CO2 and the water into the syngas composition including carbon monoxide and hydrogen.

摘要: The present disclosure provides an integrated process and a Cu/Zn-based catalyst system for synthesizing methanol from CO2 and generating electricity from hydrocarbon feedstock. The process includes steps of gasifying hydrocarbon feedstock into syngas by using oxygen and using the produced syngas as a fuel in a power generation unit, reusing a first part of an exhaust stream of the power generation unit as a reactant in the gasification unit. Using a second part of the said exhaust stream as a reactant for methanol synthesis in a methanol reactor, wherein, the second part is treated to separate CO2 and water, and CO2 is used as the reactant for methanol synthesis. Operating an electrolyzer during non-peak hours to produce hydrogen, wherein, a required stoichiometric ratio of the produced hydrogen is transferred into the methanol reactor for methanol synthesis, wherein, a Cu/Zn-based catalyst system is used for methanol synthesis through a direct hydrogenation reaction of CO2.

摘要: A method of producing a acid/metal bifunctional catalyst may include: mixing an acid catalyst, a metal catalyst, and a fluid to produce a slurry, wherein the acid catalyst is present at 50 wt % or less relative to a total catalyst weight in the slurry; heating the slurry; producing a powder from the slurry; and calcining the powder to produce the acid/metal bifunctional catalyst. Such acid/metal bifunctional catalyst would be useful in the direct conversion of syngas to dimethyl ether as well as other reactions.

摘要: The present disclosure relates to a new catalytic process for the production of methanol from carbon dioxide, comprising: (1) the conversion of carbon dioxide and hydrogen to formic acid or formate salts; (2) converting the formic acid or formate salts to diformate esters of diols; (3) hydrogenating the diformate esters to methanol and diols. The diols produced from the hydrogenation reaction can be recovered and re-used to prepare the diformate esters.
