The advanced theory of statistics

A method for continuously effecting reactions in a liquid phase in the presence of a gas and of a finely divided solid catalyst in a bubble column-cascade reactor with little or no liquid back-mixing, dwell time in the reactor being dependent on the liquid and gas throughputs, said reactor comprising a vertical column and a plurality of equidistantly-spaced, horizontally mounted, uniformly-perforated plates therein, the aperture area of each plate being dependent on the cross-sectional area of the column and the plate spacing within the column being such that adjacent plates are separated vertically by a distance at least three times the diameter of said columnar reaction zone.
