An improved catalyst assembly for vapor/liquid contact towers. Catalyst media used to promote chemical reactions is secured substantially in the liquid phase of the tower, such as in the lower portion thereof for improving mass transfer efficiency. Unlike previous process tower assemblies, wherein distillation in conjunction with chemical reaction occurs in the vapor phase or in a mixed phase, the present invention substantially confines the reaction step to the liquid phase. In this manner, the reaction is less obstructive to vapor flow within the tower, promoting better mixing and diffusion of the feed components.

An improved method of operation of a process column utilizing catalyst media therein for promoting a chemical reaction of liquid constituents, said method of operation of said column including the steps of flowing liquid downwardly and vapor upwardly within said column for interaction and mass transfer therebetween, wherein the improvement comprises the steps of defining a liquid-only region within said column, segregating vapor flow from said liquid-only region by removing said vapor from said column and preventing said vapor from being exposed to said liquid-only region and to said catalyst media, disposing said catalyst media in said liquid-only region of said column and chemically reacting said liquid constituents one with the other in said liquid-only region in the presence of said catalyst.
