Mixed-Oxide Sorbent for Moderate-Temperature Removal of Carbonyl Sulfide
Fe-Mn-Ce oxides were used to remove carbonyl sulfide from syngas at moderate temperature in this work. Tests showed that the sorbent exhibited a high reactivity and sulfur capacity. At the same time, the sorbent exhibited better performance under cyclic operation. Thermogravimetry was used to study reaction kinetics when gas contained different gases on the desulfurization reaction. It was found that the apparent reaction activation energy was smaller in the atmosphere of reaction gas contains hydrogen than that in the absence of hydrogen.
