  • Regenerable system for the removal of sulfur compounds from a gas stream
    Patent number: 10112171
    Abstract: The disclosure relates to copper oxide-based sorbents, and processes for preparing and using them. The sorbents are preferably used to remove one or more sulfur species from gas streams. The sorbents comprise a porous silica support material impregnated with CuO nanoparticles. The nanoparticles are uniformly distributed throughout the porous silica support and sulfur compounds are adsorbed on the nanoparticles.
    Type: Grant
