摘要

The laboratory reactor comprises a spiral tube, which has a succession of curves for the cocurrent downward flow of the liquid gas or liquid. The catalyst is present in the form of solid particles of diameter (D) of 0.5-4 mm. The reactor has a catalytic volume V of 10-1 cm 3. The liquid gas or liquid flows in the downward direction. The diameter of the reactor is lower than 8 mm. The reaction is a solid liquid reaction. A certain amount of inert gas is introduced in the reactor so that the superficial velocity of gas is 10% of superficial velocity of the liquid.

The diameter of the reactor is lower than 8 mm. The reaction is a solid liquid reaction. A certain amount of inert gas is introduced in the reactor so that the superficial velocity of gas is 10% of superficial velocity of the liquid. The solid catalyst has extruded or lobed shape with a diameter of 1-3 mm, or is present in the form of a ball. The catalyst is poly dispersed in which it is represented by two distinct populations of average diameter, where the ratio of the average larger diameter to average smaller diameter is greater than 3.
