  • Chlorination method
    Patent number: 4329526
    Abstract: An improvement in fluid-bed oxychlorination methods comprising in combination a generally cup-shaped container and an inverted generally cone-shaped gas distributor having a truncated apex the section of truncation defining a generally circular or polygonal opening, the lip portion of the container fitting against the similarly-shaped opening of the distributor.
    Type: Grant
    Filed: November 17, 1980

    Inventors: Melvin R. Bagley, Burton B. Crocker, John F. Pysz
  • Gas distributor apparatus for fluidized bed reactor
    Patent number: 4251926
    Abstract: An apparatus for the distribution of gas in a fluidized bed reactor comprises in combination a generally cup-shaped container and an inverted generally cone-shaped gas distributor having a truncated apex the section of truncation defining a generally circular or polygonal opening, the lip portion of the container fitting against the similarly-shaped opening of the distributor.
    Type: Grant

  • Phosphorus-vanadium-oxygen catalysts having a specific pore volume
    Patent number: 4092269
    Abstract: The prior art discloses that phosphorus-vanadium-oxygen catalysts wherein the phosphorus to vanadium atom ratio is between about 1:2 and about 2:1, and wherein at least about 20 atom percent of the vanadium is in the tetravalent state, are useful for the conversion of aliphatic hydrocarbons to maleic anhydride. It has now been found that when the pore volume of the catalysts from pores having diameters between about 0.8 micron and about 10 microns is greater than 0.02 cc/g, the catalyst is particularly useful for the conversion of saturated hydrocarbons, such as butane, to maleic anhydride.
    Type: Grant

  • Fusion of vinyl plastisol to heat-sensitive backing
    Patent number: 3950198
    Abstract: Vinyl plastisols are fused to heat-sensitive primary backings and facing yarns integral therewith and expanded thereon by the application of a heating medium in the form of high velocity steam or a high velocity gas. Although the temperature of the heating medium is above the softening point of the heat-sensitive primary backing, the velocity of the heating medium and the angle at which it is directed against the plastisol-coated, heat-sensitive primary backing results in fusion and expansion of the vinyl plastisol on the heat-sensitive primary backing without damage to the backing material or facing materials associated therewith.
