Development of Fe-based Catalysts for Purification of Coke Oven Gases

Abstract

<p>Fe-based catalysts of different geometry are developed for the purification of coke oven gases: bulk, supported on alumina and supported on alumina silicate monoliths. Adsorption and decomposition of H<sub>2</sub>S on the catalysts developed are studied. Influence of active component content, type of support material and modification by Mn and Mo on the catalyst activity in de-H<sub>2</sub>S process is elucidated. Supported monolith catalysts show superior activity over bulk and supported spherical catalysts in H<sub>2</sub>S decomposition reaction and demonstrate stable operation in ammonia decomposition process during 2 hours at 900 °C giving 100% ammonia conversion.</p>
