Dry desulfurization of simulated flue gas in a fluidized-bed reactor for a broad range of SO{sub 2} concentration and temperature: A comparison of models
- Anakara Univ. (Turkey)
In this work, dry desulfurization of simulated flue gas was investigated in a batchwise operated laboratory-scale stainless steel fluidized-bed reactor (46 x 500 mm{sup 2}) by using calcium-containing local Turkish limestone (Karaagach/MUS) which was calcined at 900 C with 5% H{sub 2}O vapor. The sulfation reaction was carried out in a broad range of temperature (200 {le} T({degree}C) {le} 900) and SO{sub 2} feedstock concentration (1000 {le} C(ppm SO{sub 2}) {le} 6000). The experimental sulfation conversion-time data were tested according to unreacted shrinking core model (SCM), changing the grain size model (GM) and random pore model (RPM). It was found that the random pore model with control of product layer (CaSO{sub 3}/CaSO{sub 4}) diffusion described the experimental data best.
