The sulfation rates of reagent grade calcium and zinc oxides and technical grade magnesium oxide with sulfur trioxide and sulfur dioxide ‐ oxygen mixtures have been measured thermogravimetrically. Experiments have been conducted to determine the rate of reaction for various particle radii (0.071‐0.151 mm), temperatures (450‐1100 K.) and concentrations of sulfur dioxide, sulfur trioxide (0.075‐0.62 moles/m 3 ), oxygen (0‐1.5 moles/m 3 ). Experimental results are presented which compare the sulfation rates of each basic oxide with sulfur dioxide and sulfur trioxide at different temperatures. The rate of sulfation of different oxides are compared under the same experimental conditions.
