Abstract
A method of preparing a column for a reaction with distillation process utilizing a solid particulate catalyst includes the steps of providing a plurality of vertically spaced apart distillation devices, coupling these devices with a plurality of vertically extending horizontally spaced catalyst enclosing containers, extending at least some of the containers through at least two successive distillation devices, then loading a particulate catalyst into the containers to form a catalyst bed whereby distillation and catalytic reaction may occur simultaneously in the column. The method also encompasses a process for concurrent catalytic reaction with distillation which includes the foregoing steps as well as the steps of feeding a liquid stream to the column reactor and onto the distillation devices while a vapor stream moves vertically up through the distillation devices while products of reaction and distillation are withdrawn from the reactor.
