Abstract
Improved catalyst assemblies for vapor/liquid contact towers. Bundles of catalyst media used to promote chemical reactions are disposed substantially in the vapor phase of the tower, such as beneath trays therein for improving mass transfer efficiency. Unlike previous assemblies, wherein distillation in conjunction with chemical reaction occurs in the liquid phase or in a mixed phase, the present invention substantially confines the reaction step to the vapor phase. In this manner, the reaction is less obstructive to fluid flow within the tower, promoting better mixing and diffusion of the feed components in the vapor phase. In addition, less turbulence is created and the handling of vapors generated from an exothermic reaction is facilitated. The design and control of the chemical reaction may also be more precise with distinct and separate zones of catalyst media
