The present invention relates to a distribution device intended for a gaseous effluent produced by a chemical reaction, comprising at least two inlet ways and two outlet ways. This device comprises at least one closed-loop line divided into four sections by four controlled sealing elements, and each one of said four ways communicates with a single section so that the inlet ways are connected to two opposite sections and said outlet ways are connected to the other two sections.

Distribution device for automatic catalyst evaluation multi-reactors

A method and to an equipment carry out measurements on an effluent resulting from a chemical reaction taking place in a reactor containing a catalyst. The method includes, in combination, injecting at least one feedstock into each of at least two reactors, separating the gas and liquid phases downstream from each reactor, sending the separated gas phase to be measured and analyzed while the other gas phases coming from the other separators are discharged, sending the separated liquid phase to be analyzed and measured, and automatically monitoring and controlling the chemical reaction in the reactors, the analysis and measurement cycle performed on the gas phase and the analysis and measurement cycle performed on the liquid phase.

Automatic multi-reactor catalyst evaluation method and device with a heavy feedstock

A method and an equipment carry out measurements on an effluent resulting from a chemical reaction taking place in a reactor containing a catalyst. The method includes, in combination, injecting at least one feedstock into at least two reactors, sending the effluent coming from one of the reactors for analysis and measuring controlling the pressure and the temperature of the effluent in the circuit contained between downstream from the reactors and upstream from the analysis device, and allowing automatic monitoring and control of the chemical reaction in the reactors and of the analysis and measurement cycle performed on the effluent produced by the reaction.
