  • Patent number: 5556984
    Abstract: The saturated hydrocarbons, typically alkanes having from 3 to 12 carbon atoms, e.g., propane, are selectively ammoxidized into .alpha.,.beta.-unsaturated nitriles and olefins, e.g., acrylonitrile and propylene, by reacting such alkanes with ammonia and oxygen, in vapor phase and in the presence of a solid catalyst, such solid catalyst including a catalytically effective amount of an active catalytic phase which comprises molybdenum, oxygen and at least one element selected from among the alkaline earth metals, Mn, Fe, U, La, Co, Ni, Zn, Ag, Cd, W, Zr, Pb, Te, Ga, Al, B, Nb and Ta.
    Type: Grant
    Filed: March 23, 1994
    Date of Patent: September 17, 1996

  • Patent number: 5336804
    Abstract: The alkanes, e.g., propane, are ammoxidized into admixtures containing .alpha.,.beta.-unsaturated nitriles, e.g., admixture of acrylonitrile and propylene, by reacting such alkane with ammonia and oxygen, in vapor phase, in the presence of a catalytically effective amount of a solid catalyst, at least one active catalytic phase of which having the empirical formula (I):VSb.sub.a Bi.sub.b O.sub.x (I)optionally also containing iron and/or gallium and/or indium, in which a is a whole or fractional number equal to or greater than 1, b is a whole or fractional number equal to or greater than 0.01, and x is a whole or fractional number provided by the oxidation number of the other elements of the at least one active catalytic phase.

  • Patent number: 5334743
    Abstract: The alkanes, e.g., propane, are selectively converted (ammoxidized) into admixtures comprising .alpha.,.beta.-unsaturated nitriles, e.g., acrylonitrile, by reacting same with ammonia and oxygen, in vapor phase, and in the presence of a catalytically effective amount of a solid catalyst, the catalytically active phase of which comprising (1) molybdenum, vanadium and oxygen and (2) at least one of the elements, manganese, zinc, cobalt, copper, lithium, sodium, potassium and silver.

  • Patent number: 4991322
    Abstract: The invention relates to a device for affixing cutter drums on an apparatus designed to cut trenches in the ground.The driver includes a revolving plate 4 disposed perpendicular to its axis and to the end of the latter, the plate having on its periphery a convex polygonal shape 9. A cutter drum 8 is provided with a portion 8a including a central hollow of concave polygonal shape 10 corresponding to the convex polygonal shape 9 of the plate 4 and of slightly greater dimensions. Bolts 11 unite the cutter drum 8 to the said plate 4 such that the rotational driving of the cutter drum 8 by the plate is performed through the medium of the aforesaid polygonal surfaces 9, 10 which come into engagement with one another.
