Abstract
Abstract A method and apparatus for conducting catalytic chemical reactions and fractionation of the reaction mixture, comprising and feeding reactants into a distillation column reactor contracting said reactant in a liquid phase with a fixed bed catalyst in the form of a contact catalyst structure, consisting of closed porous containers containing the catalyst for the reaction and a clip means to hold and support said containers, which are disposed above, i.e., on the distillation trays in the tower. The trays have weir means to provide a liquid level on the trays to substantially cover the containers. In other words, the trays function in their ordinary manner with the addition thereto of the catalyst. The reaction mixture is concurrently fractionated in the column.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
117 words
In combination a distillation tray and a contact catalyst structure said tray having a bottom and sides defining a weir means for holding a liquid level on the bottom of said tray, said tray catalyst structure comprising a plurality of porous closed containers, containing therein solid particulate catalyst, and a plurality of clip means mounted on said bottom of said tray for holding and spacing said containers as a unit, each said clip means comprising at least one structure comprising a base member mounted on said bottom and a plurality of resilient pairs of members upwardly extending from said base member substantially perpendicular thereto for grasping and holding a said container above the bottom of said tray.
