The current industrial method for removal of sulfur from fuels is hydrodesulfurization (HDS), which is a high temperature, high pressure catalytic process. This makes HDS a very costly option for deep desulfurization. Moreover, HDS is not effective for removing heterocyclic sulfur compounds such as dibenzothiophene (DBT) and its derivatives, especially 4,6 …

However, desulfurization gypsum has some own features as relatively finer solid size (60 μm), high water content (10–15%) and impurity, these have special effect on the utilization. The desulfurization gypsum are widely utilized in cement retarder, building material, embedment and neutralizer or regulator of soil in agriculture [3, 4].
