Abstract
The autoclave of the present invention includes an impeller having a conduit to recirculate or introduce a molecular oxygen-containing gas into the slurry. The outlets for the gas can be located in the blades of the impeller for thorough dispersion of the gas bubbles in the slurry. A sparge tube for introducing an additional molecular oxygen-containing gas into the slurry can be used in conjunction with the impeller to provide a high molecular oxygen transfer rate to the slurry.
