A new synthetic regenerable sorbent was developed as an alternative to limestone and dolomite for regenerative sulfur capture in fluidized bed combustion ( FBC of coal. The sorbent consists of CaO (8‐9 wt%) on a spherical 3 mm diameter γ‐Al 2 O 3 support. A shrinking unreacted core model ( SURE 2) is proposed to describe the sulfation process. Experiments have been carried out in a 12 mm internal diameter fixed bed reactor, a 0.05 m ID fluidized bed reactor and a thermobalance. The results obtained for all three reactors are in good agreement with the predictions of the SURE 2 model.
