摘要： A process for catalytically directly producing hydrogen peroxide (H2O2) product from hydrogen and oxygen-containing feeds by contacting them with a supported noble metal phase-controlled catalyst and a suitable organic liquid solvent having a Solvent Selection Parameter (SSP) between 0.14×10−4 and 5.0×10−4 at reaction condition of 0-100° C. temperature and 100-3,000 psig pressure. Unconverted feed gas and organic liquid solvent solution are usually recovered and recycled back to the reactor along with any recovered catalyst. If desired, the hydrogen peroxide product can be fed together with an organic chemical feedstock such as propylene and with the organic liquid solvent solution into a second catalytic reaction step which oxidizes the feedstock to produce a desired crude oxidized organic product such as propylene oxide, which may be purified by distillation steps and recovered from the solvent solution.

摘要： A bi-functional oxidation catalyst and process for catalytic oxidation and removal of nitrogen oxides (NOx) from combustion gases derived from combustion of carbonaceous fuels such as coal, oil, or natural gas. The bi-functional catalyst includes adsorption and oxidation function metal oxides provided in adjacent close intimate contact by utilizing a binding agent, such as carboxylic acid and calcining to provide a metal oxide complex having a crystalline form. Such nitrogen oxides (NOx) contained in the combustion gases are initially catalytically oxidized to at least about 50 vol % NO2 and some higher oxides by contact with the bi-functional catalyst at 170-550° F. temperature. The combustion gas containing the partially oxidized NOx is then preferably further chemically oxidized by being mixed with a chemical oxidant such as ozone (O3) in a molar ratio of the chemical oxidant3 to NOx in the range of 0.5:1-1.2:1 to produce higher oxides of nitrogen such as substantially N2O5. The further treated combustion gas containing the N2O5 is next scrubbed with a suitable scrubbing liquid such as water to effectively remove the nitrogen oxides (NOx) and produce a clean treated flue gas stream containing less than about 15 ppm nitrogen oxides and suitable for environmentally safe discharge to the atmosphere.

摘要： Supported catalysts include an inorganic solid support such as silica that is functionalized to have inorganic acid functional groups attached thereto. The functionalization of the support material is optimized by (i) limiting the amount of water present during the functionalization reaction, (ii) using a concentrated mineral acid or derivative thereof, and/or (iii) increasing the reaction temperature and/or reaction pressure. The acid-functionalized support material serves as a support for a metal nanoparticle catalyst. The nanocatalyst particles are preferably bonded to the support material through an organic molecule, oligomer, or polymer having functional groups that can bind to both the nanocatalyst particles and to the support material. The supported catalysts can advantageously be used for the direct synthesis of hydrogen peroxide from hydrogen and oxygen feed streams.
