Shaping Technology of Coal Gas Sorbents by Using a Spray Dryer
E-mail:
The goal of this study was to develop HTHP sorbents for adaptation in fluidized bed desulfurizers or Transport Reactors. For this purpose, we shaped zinc-based sorbents (ZAC series) by using a spray dryer with a pressurized nozzle atomizer. To prepare the slurry for spraying, raw materials in submicron units and organic additives were used. We characterized the sorbents by SEM, XRD, Mean Particle Size Analysis, BET Surface Area and Attrition Ratio. The mean particle size was about 112 μm, the attrition resistance was very good and the TGA sulfur capacity of the fresh sample was calculated at about 23-24 wt%.
