Abstract

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.
