摘要： A method of modifying a zeolite catalyst to increase para-xylene selectivity of the zeolite catalyst in toluene methylation reactions is provided. The method includes forming a slurry of a ZSM-5-type zeolite and an aqueous solution of a phosphorus compound. Water is removed from the slurry to provide a non-steamed, phosphorus treated ZSM-5 zeolite catalyst without deposition of phosphorus onto the catalyst by organophosphorus vapor deposition. The resulting non-steamed, phosphorus treated ZSM-5 zeolite catalyst has a pore volume of from 0.2 ml/g or less and provides greater than 80% para-xylene selectivity of mixed xylenes when used in toluene methylation.

摘要： A catalyst composition for the vapor phase ammoxidation of alkanes and olefins of the general empirical formulae:

        VSb a M b O x



        VSb a M b M' b' O x



        VSb a M b Q c O x



        VSb a M b Q c Q' c' O x

wherein M and M' are at least one element selected from magnesium, aluminum, zirconium, silicon, hafnium, titanium and niobium, M and M' being different, Q and Q' are at least one element selected from rhenium, tungsten, molybdenum, tantalum, manganese, phosphorus, cerium, tin, boron, scandium, bismuth, gallium, indium, iron, chromium, lanthanum, yttrium, zinc, cobalt, nickel, cadmium, copper, strontium, barium, calcium, silver, potassium, sodium and cesium, Q and Q' being different, a is 0.5 to 20, b is 2 to 50, b' is 0 to 50, c is 0 to 10, c' is 0 to 10 and x is determined by the valence requirements of the elements present. The catalyst composition containing isolated vanadium and antimony species in an inert matrix is prepared by incorporating respective compounds of vanadium and antimony into the oxide of at least one or more M and adding by co-precipitation or impregnation one or more optional Q in the relative atomic proportions indicated by the subscripts.
