Reactor for kinetic study of gas-liquid or liquid catalytic reactions e.g. selective hydrogenation, comprises internal wires uniformly distributed on a section of the reactor and completely crossing a catalytic zone

摘要

The reactor (1) for kinetic study of gas-liquid or liquid catalytic reactions, comprises internal wires (3) uniformly distributed on a section of the reactor and completely crossing a catalytic zone. The reactor contains a catalytic volume of less than 100 cm 3. The catalyst is present as solid particles having diameter of 0.5-4 mm. The number of internal wire is defined such that the greatest distance between a grain of catalyst and the internal or the nearest wall is less than a length l and represented by an equation as given in the specification.

The reactor contains a catalytic volume of less than 100 cm 3. The catalyst is present as solid particles having diameter of 0.5-4 mm. The number of internal wire is defined such that the greatest distance between a grain of catalyst and the internal or the nearest wall is less than a length l and represented by an equation as given in the specification. The internal wires are straight and have a cylindrical section, constituted for wholly or partly by thermocouples, and placed before the loading phase and left in place during the phase of operation.
