Abstract
A method for conducting catalytic chemical reactions and fractionation of the reaction mixture comprising feeding reactants into a distillation column reactor contracting said reactant in liquid phase with a fixed bed catalyst in the form of a contact catalyst structure consisting of closed porous containers containing the catatlyst 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.
Claims9
A contact catalyst structure comprising a plurality of porous closed containers, containing therein solid particulate catalyst and clip means, for holding and spacing said containers as a unit for disposition above a distillation tray of a distillation column, said clip means comprising at least one structure comprising a base member and a plurality of resilient pairs of members extending substantially perpendicular therefrom for grasping and holding said containers, one each between each of said pair of resilient members.
A contact catalyst structure comprising a plurality of porous closed containers which are wire mesh containing therein solid particulate catalyst in the range of 0.25 to 1 mm diameter and clip means for holding and spacing said containers as a unit for disposition above a distillation tray of a distillation column.
A contact catalyst structure comprising a plurality of porous closed containers which are plastic mesh, containing therein solid particulate catalyst in the range of 0.25 to 1 mm diameter and clip means for holding and spacing said containers as a unit for disposition above a distillation tray of a distillation column.
