A Kinetic Model for Alumina Sulfation

The kinetics and mechanism of SO2oxidation by O3on mineral dust

“…Many studies focus on the effect on different catalysts which are used for desulfurization of fuel gas, liquids or waste gases. [8][9][10][11][12][13][14][15][16][17] These are mainly exploring the reaction mechanism and are performed at high temperatures. Other studies focus on the effect SO 2 adsorption on buildings including experiments on substrates such as marble and limestone.…”

From Gas to Liquid Phase Sulfidation: An IR Spectroscopy Study

“…After gas sulfidation only one band is visible at 1372 cm -1 (Fig. 1B) attributed to the presence of a small amount of sulfate on the alumina support [28,29]. On the contrary, after liquid phase sulfidation or gas phase sulfidation followed by thiophene exposure, no formation of sulfate species was evidenced.…”

Activity and sulfur resistance of CuO/SnO2/PdO catalysts supported on γ-Al2O3for the catalytic combustion of benzene

“…During sulfur poisoning, when SO 2 is added into the reaction, SO 2 is converted to SO 3 at a certain temperature and reacts with the active sites to form sulfate species, which results in catalyst poisoning. In previous studies, 17,32,33 the formation of sulfate on the catalyst surface is the primary source of the loss of catalytic activity. In addition, the sulfur poisoning mechanism of PdO/g-Al 2 O 3 is more complex, because g-Al 2 O 3 is a sulfatable support.…”
