Abstract

Previously we have reported that H₂S reacts with iron oxide to form FeSx, which captures elemental Hg vapor (Hg⁰) as HgS. In this work, we studied the relation between the rate of Hg⁰ removal and the rate of sulfidation of iron oxide using a laboratory-scale fixed-bed reactor for the Hg⁰removal and thermo-gravimetric analysis (TGA) for the sulfidation of iron oxides in a temperature range of 60 to 100°C. Supported and unsupported iron oxides pre-Treated (dried and calcined) at various temperatures were utilized. The relationship between sulfidation and Hg ⁰ removal is not yet clear. The presence of CO in the feed gas suppressed the weight gain of iron oxide, however the Hg⁰ removal capacity was unaffected by the presence of CO. In the case of Fe ₂O3_--110 (dried at 110°C), generation of COS was confirmed during the removal of Hg⁰.
