Modeling SO trapping on a copper-doped CuO/SBA-15 sorbent material.

A mixture of SO and air was continuously injected in a fixed bed reactor containing a CuO/SBA-15 sorbent material and submitted to an isothermal temperature between 325 and 400 °C. The SO emissions were measured at the exit of the reactor. Different isothermal temperatures, different injected SO concentrations and different sorbent masses, all representative of industrial conditions, were tested.
