Oxidation of Sulfur Dioxide to Sulfuric Acid over Activated Carbon Catalyst Produced from Wood

Novel methane activation by sulfur dioxide and molecular oxygen via trifluoroacetylsulfuric acid

“…3 There have been efforts to efficiently transform SO 2 into useful compounds such as sulfur trioxide (SO 3 ) or sulfuric acid (H 2 SO 4 ) for practical use. Typically, SO 2 is converted to SO 3 by reacting with O 2 in the presence of catalysts such as platinum or activated carbon through energy-intensive processes, 4 requiring the development of a new cost-efficient sulfonation technique using SO 2 .…”

Non-woven fabric activated carbon produced from fibrous waste biomass for sulphur dioxide control

“…They reported that the adsorption of SO2 was influenced by the alkali used in the chemical activation (KOH) through chemical adsorption. Katada et al (2003) investigated the removal of sulphur dioxide using activated carbons produced from several waste biomass, including waste urban wood and coconut shells in a fixed bed reactor at low temperature (45 °C). They reported high removal efficiencies for some of the biomass derived activated carbons (>90%) which they attributed to the pore structure, surface chemistry and hydrophobic/hydrophilic properties of the carbons.…”
