Abstract
A process and apparatus is provided which are effective for improving CO mass transfer. The process includes introducing syngas into a reactor vessel through a gas sparger located below a liquid level in the reactor vessel. The syngas being introduced at a flow rate effective for maintaining a pressure inside of the reactor vessel of at least about 1 psig. An agitation energy of about 0.01 to about 12 kWatts/mmedium is provided. The process is effective for providing a volumetric CO mass transfer coefficient of about 100 to about 1500 per hour.
