HYDROTALCITE SULFUR OXIDE SORPTION

摘要

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 SOX 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.
