    Abstract: The present invention relates to a method for the preparation of phosphomolybdic acid based catalysts by forming a solution of hydrated phosphomolybdic acid in a substantially anhydrous alkyl alcohol, optionally adding a base to the solution, evaporating the solution to yield a catalyst powder and thereafter drying and calcining the powder to form the active catalyst. A second method for preparation is also provided and includes the steps of forming a solution of hydrated phosphomolybdic acid in a substantially anhydrous alkyl alcohol evaporating the solution to form a concentrate, impregnating a catalyst support material with the concentrate, contacting the impregnated support with ammonia gas in an amount sufficient to form an insoluble precipitate of ammonium alkyl phosphomolybdic acid within the pore structure of said support material and thereafter drying and calcining said impregnated support material so as to form a coated catalyst.

    Abstract: PROCESS FOR THE PREPARATION OF DIOLEFINS FROM OLEFINS A catalyst is disclosed wherein the atomic ratios are disclosed by the empirical formula: Aa Cc Dd Fee Bif Mog Ox wherein A is chromium, tellurium, germanium, tungsten, manganese, thorium, niobium, praseodymium, cerium, lanthanum, zinc or mixture thereof; C is an alkali metal, alkaline earth metal, Tl, In, Ag, Cu, Sn, Sb, rare earth metal or mixture thereof; D is nickel, cobalt, magnesium, zinc, cadmium, manganese, calcium or mixture thereof; A is not the same as D; and wherein a is greater than zero to about 4; c is 0 to about 4; d is 0.1 to about 20; e and f are 0.01 to 12; g is 10 to 15; and x is the number of oxygens required by the valence states of the other elements present. This catalyst may be employed for the oxidative dehydrogenation of olefins of 1 to about 10 carbon atoms.

    Abstract: 1409599 Purifying NH 3 plant effluent STANDARD OIL CO 19 June 1973 [22 June 1972] 28937/73 Heading C1A A gas stream containing at least 90% by vol. steam and 0À1-10% by vol. of NH 3 and/or organic compounds with up to 6 carbon atoms is contacted with a catalyst containing the oxides of Cu, Fe, Mn, Bi, Ni, Co, U, Mo, V, Cr, W, Pd, Pt, Ag, Zn, alkali metal, alkaline earth metal, Sn and/or Sb at a temperature of 200-800‹ C. to oxidize the NH 3 or organic compound, wherein the said gas stream is obtained as a result of (a) stripping a hot K 2 CO 3 solution to form a gas stream containing H 2 O, CO 2 , together with NH 3 and/or the organic compounds, (b) condensing or washing the gas stream with H 2 O to form an aqueous stream containing NH 3 and/or the organic compounds and (c) steam stripping the aqueous stream to obtain the said gas stream containing NH 3 and/or the organic compounds. O 2 in the form of air is preferably added to the gas stream prior to catalysis. The K 2 CO 3 solution containing the CO 2 together with NH 3 and the organic compounds may be that formed on scrubbing a gas stream formed on catalytic oxidation of CH 4 with steam and air to form H 2 and CO 2 , in which case the organic compounds are CH 3 OH, HCOOH and HCHO.
