Abstract

AbstractThe Energy & Environmental Research Center (EERC) participated in a project with Owens‐Corning Fiberglas Corporation (OCF) to test high‐temperature fabric filters coated using a sol‐gel process with a proprietary form of a vanadium/titanium (V/Ti) catalyst. The catalyst‐coated S‐glass fabric filters are targeted for use in a power plant or industrial hot‐side baghouse facility for simultaneous NOx and particulate control. Issues pertaining to the successful development and marketing of this technology, such as catalyst and filter durability, NOx and particulate control capabilities, ammonia slip levels, and catalyst deactivation were addressed. As part of this project, bench‐scale experiments were performed at the EERC to determine the effects on catalyst reactivity and fabric integrity of 1) suspected selective catalytic reduction (SCR) catalyst poisons typically found in Western coal ash, and 2) exposure to a water or acid dewpoint as a result of an operational upset in a baghouse facility.
