  • Method of removing hydrogen sulfide from hot gas mixtures
    Patent number: 5700439
    Abstract: Coated sulfur sorbent particles have been found to resist agglomeration when used in industrial processes generating sulfur vapors at elevated temperatures, even in the presence of hydrogen chloride and/or water vapor. These coated sulfur sorbents have been found to improve vapor phase sulfur sorption processes at elevated temperatures in either single or multiple sulfidation cycles followed by regeneration.
