Abstract

Liquid and gas materials are reacted in the presence of a catalyst in a reactor of the dispersed bed type which comprises a plurality of superposed chambers through which the catalyst progressively drops, its rate of transfer from one chamber to another being controlled by injecting an auxiliary fluid into downcomers through which the catalyst is forced to pass.
