    摘要： A method for manufacturing of an improved attrition resistant catalyst having an oxide-rich surface layer involving forming an aqueous slurry comprising; catalyst, catalyst precursor or catalyst support particles (e.g., vanadium/phosphorus oxide, V/P/O catalyst), a large particle colloidal oxide sol (e.g., 200 Å, 600 Å, 750 Å colloidal silica, sodium stabilized) as the major oxide-rich surface layer forming component, and a second oxide-rich surface layer forming component solution wherein the solute is selected from the group consisting essentially of a precursor of the oxide-rich surface with average particle size no greater than 5 nm (e.g., aqueous silicic acid or polysilicic acid), a colloidal oxide sol wherein oxide particles in the sol have an average size below 10 nm (e.g., 50 Å colloidal silica), and mixtures thereof and then spray drying the slurry to form porous microspheres of attrition resistant catalyst; and, calcining/activating the spray dried microspheres. Such a catalyst is particularly useful and exhibits improved performance in oxidation processes such as the catalytic air oxidation of butane to maleic anhydride.

    摘要： A catalyst comprising vanadium phosphorus oxide combined with a thermally conductive material is particularly useful for the selective hydrocarbon oxidations (e.g., butane to maleic anhydride) and can be prepared by forming a suspension comprising a vanadium (IV) phosphate compound in a liquid medium (via hydrochloric acid digestion of V2O5 and H3PO4 in an aqueous solvent or via heating vanadium pentoxide with at least one substantially anhydrous unsubstituted alcohol having 1-10 carbon atoms, 1-3 hydroxyl groups free from olefinic double bonds to form a feed of vanadium pentoxide reduced to a valence between 4 and 4.6, and then contacting the feed with a solution of orthophosphoric acid and at least one unsubstituted alcohol), adding a thermally conductive material to the suspension under agitation at moderated temperature between 40° C. and 120° C., followed by drying, optionally but preferably washing and calcining (either in situ or ex situ) the material thus formed.

    摘要： A process for the preparation of a vanadium/phosphorus mixed oxide catalyst precursor is described, comprising the reaction of a vanadium source in selected organic media in the presence of a phophorus source. The medium comprises: (a) isobutyl alcohol or a mixture of isobutyl alcohol and benzyl alcohol and (b) a polyol in the weight ratio (a) to (b) of 99:1 to 5:95. After its activation, the vanadium/phosphorus mixed oxide catalyst precursor is an excellent catalyst in the conversion of non-aromatic hydrocarbons like n-butane to malic anhydride.
