  • Flue gas desulfurization sorbent
    Patent number: 4039478
    Abstract: Sulfur dioxide is removed from gas mixtures such as flue gas containing the same by contacting the gas mixture with a solid sorbent comprising a porous gamma-alumina base, about 2 to 20 percent by weight (based on alumina) of a coating of a refractory oxide such as titanium dioxide, zirconium dioxide, or silica, and an active material, such as copper oxide, which is capable of selective removal of sulfur oxides from a gas mixture.
    Type: Grant
    Filed: January 10, 1975
    Date of Patent: August 2, 1977
