摘要： A method for regenerating spent supported metal catalysts comprising treating the spent catalyst with an organo-metallic complex forming agent having an ionization constant pK1 of at least 2.5. The catalyst activity is restored to an activity level near to or greater than the fresh catalyst. The regeneration method is particularly useful for regenerating spent palladium catalysts on an alumina support as utilized for the hydrogenation of ethyl anthraquinone (EAQ) in the production of hydrogen peroxide.

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： A process for producing oxidized organic chemical products from various organic chemical feedstocks utilizing as oxidant hydrogen peroxide (H2O2) produced by noble metal nanocatalysis with high selectivity at low hydrogen concentration. The organic chemical oxidation process step can optionally be carried out in situ concurrent with the production of hydrogen peroxide or in a two stage process. In the two stage process, the hydrogen peroxide intermediate is directly produced by noble metal nanocatalysis from hydrogen and oxygen feeds plus a suitable solvent in a first catalytic reaction step. An organic chemical feedstock and the hydrogen peroxide intermediate and solvent solution are fed into a second catalytic reactor to produce an oxidized organic chemical product.

摘要： Novel methods for manufacturing carbon nanostructures (e.g., carbon nanospheres) that are highly dispersed include forming a precursor composition, polymerizing the precursor composition, extracting water from the polymerized carbon material using an organic solvent, and carbonizing the polymerized material (e.g., through pyrolysis) to form the carbon nanostructures. The extraction-treated polymerized carbon material forms carbon nanostructures that are less agglomerated than carbon nanostructures manufactured using a similar technique without solvent extraction of water.
