| مستخلص: |
Desulphurisation sorbent properties, including desulphurisation activity and mechanical strength, are important in the sulphidation/regeneration cycle for high-temperature coal gas desulphurisation. In this paper, α-Fe2O3 desulphurisation sorbent was prepared and the changes in its mechanical strength and the surface morphology after regeneration in O2, SO2 and SO2-O2 atmospheres were measured with a particle strength tester and by scanning electron microscopy. The mechanical strength of the sorbent was generally higher after regeneration, although the formation and decomposition of sulphate during regeneration decreased the mechanical strength of the sorbent. The sulphate formation and decomposition depended on the O2 and SO2 concentration and the regeneration temperature. The mechanical strength was also increased by the sorbent sintering.
