Study on Desulfurization Abilities of Some Commonly Used Desulfurization Agents
View through CrossRef
The desulfurization abilities of some commonly used agents, namely fluidized CaO, CaC2, commercial‐CaO, Mg, MgO, CaO · MgO, and mixtures of commercial‐CaO–Mg were studied and compared under the same experimental conditions in a laboratory furnace at 1773 K. The desulfurization mechanisms of CaO · MgO, commercial‐CaO, and mixtures of commercial‐CaO and Mg were also studied. While fluidized CaO showed the best performance, commercial‐CaO mixed with 20 mass% Mg achieved the second best desulfurization. Mg‐granules performed slightly better than CaC2 and commercial‐CaO, but somewhat less satisfactory compared to fluidized CaO and commercial‐CaO–Mg mixtures. Since only the CaO portion in CaO · MgO functioned to take up sulfur, additional 70% mass had to be added to achieve the same desulfurization level. The poor ability of commercial‐CaO in comparison to fluidized CaO powder was due to both its less reactive surface and agglomeration of the particles.
