Automatic multi-reactor catalyst evaluation method an device with in-line analysis without liquid-gas separation

An equipment intended for measurement on an effluent resulting from a chemical reaction taking place in a reactor containing a catalyst, characterized in that it comprises in combination:

• at least two reactors,
• means for injecting at least one feedstock into each reactor,
• distribution means for sending the effluent coming from one of the reactors to analysis and measuring means while the other effluents coming from the other reactors are discharged, wherein said distribution means comprise at least two inlet ways and two outlet ways, at least one closed-loop circuit divided into four sections by four controlled sealing elements, each 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,
• means for controlling the pressure and the temperature of said effluent in the circuit contained between downstream from the reactors and upstream from the analysis means, including said distribution means, and
• means intended for automatic monitoring and control of the chemical reaction in said reactors and of the cycle of analysis and measurement on the effluent produced by said reaction.
