| Sumario: | Adsorption and reaction studies were carried out for the catalytic oxidation of sulfur dioxide in a slurry reactor, using activated carbon as catalyst, at room temperature and atmospheric pressure. It was verified that the rate is first order in oxygen and zero order in sulfur dioxide. The reaction rate is controlled by gas-liquid mass transfer and by diffusion and reaction in the catalyst particles. The contribution of each step varies with the operative conditions such as particle diameter, stirring rate, type of distributor and catalyst load. Internal diffusion resistance in the particle is significant; the effectiveness factor is less than 0.9 even for particles of about 0.006 cm diameter. © 1989. |
