Industrial scale endothermic pilot plant system

A process for assessing a performance of a catalyst, comprising:

• heating a mixture of hydrocarbon feedstock and a gas with a heater to form a vaporous hydrocarbon mixture;
• introducing a first portion of the vaporous hydrocarbon mixture to a chemical reactor and a second portion of the vaporous hydrocarbon mixture into a test reactor via a conduit in flow communication with the chemical reactor and with the test reactor, said chemical reactor and said test reactor each containing a catalyst;
• circulating said mixture in said test reactor to react said mixture with the catalyst in the test reactor to produce an effluent;
• testing said effluent to determine the performance of the catalyst in the test reactor in said mixture;
• reheating an effluent from the chemical reactor with a further heater;
• conducting a first portion of the reheated effluent to a further chemical reactor and a second portion of the reheated effluent to a further test reactor via a conduit in flow communication with the further chemical reactor and the further test reactor, said further chemical reactor and said further test reactor each containing a catalyst;
• testing an effluent from the further test reactor to determine the performance of the catalyst in the further test reactor;
• removing the catalyst contained in the chemical reactor and regenerating said catalyst from the chemical reactor in a regenerator to produce regenerated catalyst;
• introducing a first portion of the regenerated catalyst to the chemical reactor and a second portion of the regenerated catalyst to the test reactor, wherein the regenerated catalyst replaces the catalyst previously contained in the test reactor;
• and
• introducing at least one further portion of the regenerated catalyst to at least one further test reactor via a conduit in flow communication with the further chemical reactor and the at least one further test reactor, wherein the regenerated catalyst replaces the catalyst previously contained in at least one further test reactor.
