SULFUR OXIDE SORPTION WITH LAYERED CHLORITE-TYPE CONTACT SOLIDS

摘要

An improved process for removing sulfur values from a gas containing sulfur oxide(s) by contacting the gas, at process temperatures and other conditions, with a novel catalyst comprising a mixture of chlorite and hydrotalcite both having high magnesia content. Further improvement in de SOX provides that at least the high magnesia chlorite in run through the process in a recycle mode. It has been found that the second and subsequent passes of the catalyst through the process further enhances removal of SOx.
