ABSTRACT
The solid-catalyzed reaction of a gas with a liquid can be carried out in a slurry reactor, where fine catalyst particles are suspended in the liquid, or in a fixed bed of catalyst pellets, where gas and liquid flow continuously through the bed. For both types, there are several mass transfer steps to consider in modeling the reactor, since the gas dissolves and diffuses into the liquid and then both reactants diffuse to the catalyst and into the pores. The models are therefore more complex than those given in Chapter 7 for gas absorption plus reaction in a liquid.
