The report summarizes trace element measurements made at several coal gasification facilities. Most of the measurements were made as part of EPA's source testing and evaluation program on low- and medium-Btu gasification. The behavior of trace elements is discussed in light of their distribution from feed coal to various discharge, product, and by-product streams. The summary provides a basis for decisions concerning monitoring needs at coal gasification facilities. The stream flow data and trace element concentration measurements were typically not precise or accurate enough to make quantitative conclusions concerning trace element behavior in the gasifiers. However, some general trends in element distribution are apparent. Elements that consistently had more than 70% of their total inlet mass partition to the bottom ash or slag included Al, Ba, Co, K, U, W, and Zr. Other elements had consistently less than 70% of their mass partition to the bottom ash, and had significant mass flow in the overhead gas and aerosols.
