Oxidation of SO2 in a Trickle Bed Reactor Packed with Activated Carbon at Low Liquid Flow Rates

Abstract

In this study, the oxidation of SO 2 on activated carbon (AcC) by using distilled water and air was carried out in a laboratory scale trickle bed reactor (TBR). Distilled water and air containing 1.7 % (v/v) SO 2 were fed co-currently downward through a fixed bed of AcC particles in a range of 1±7 cm 3 /s and 10±27 cm 3 /s respectively. H 2 SO 3 /H 2 SO 4 solutions were the products obtained in the liquid phase. Steady-state experiments were performed in a column of 0.15 m packing height and 0.047 m column diameter at 20 C and atmospheric pressure. Experimental reaction rates of this study were compared with those of other studies on the basis of plug flow model of Mata-Smith given in literature.

Enhanced BTX Production in Refineries with Sulfur Dioxide Oxidation by Thermal Integrated Model

“…But due to the significant industrial and environmental impacts, also enhancement of the net profit of a plant, the catalytic oxidation of SO 2 to sulfur trioxide (SO 3 ) has been employed in numerous industrial processes. Suyadal et al studied on oxidation of SO 2 in a trickle‐bed reactor packed with activated carbon at low liquid flow rates. Also, a comparison between catalytic oxidation of SO 2 at two‐phase up‐flow and down‐flow in fixed‐bed reactors was performed by Iliuta et al .…”
