  • Hydrotalcite contact materials
    Patent number: 6156696
    Abstract: Hydrotalcite-like contact materials are stable in the crystalline oxide structure and essentially reversible in anion exchange. Large crystalline sheet materials having increased sorption of SO.sub.X are provided by incorporation of certain organic acid anionic species to modify the hydrotalcite/brucite structure. Typical industrial applications include sulfur removal from fluid catalyst cracking process, cold-side combustion gas sulfur abatement and cleaner coal gasification.
