. What are the differences between sulfur-resistant cobalt-molybdenum catalysts, copper-based catalysts, and iron-based catalysts?
Iron-based catalysts have a high operating temperature and are inexpensive. Cobalt-molybdenum catalysts are tolerant to a wide range of temperatures and sulfur, whereas copper-based catalysts are not resistant to sulfur and require strict temperature control. In terms of CO removal efficiency, copper-based catalysts perform the best.
