Patent ID: 7390664

Claim:
A high-throughput device for evaluating fast deactivating catalysts comprising: two or more reaction vessels containing catalyst, each of said reaction vessels having at least one inlet stream and at least one outlet stream wherein one reaction vessel is on-duty and the remaining one or more reaction vessels are off-duty, said inlet streams being in direct communication with an inlet distribution system, said outlet streams being directed by an outlet distribution system, said inlet distribution system having two feed streams wherein one feed stream comprises a hydrocarbon reactant for porting to the on-duty reaction vessel and the second feed stream comprises a treat gas for simultaneously porting to the remaining one or more off-duty reaction vessels for pretreatment of catalyst, wherein said treat gas is selected from the group consisting of sulfiding fluids, activation fluids, poisoning fluids and reduction fluids and contains one or more components that react with the catalyst to assist with sulfiding, activation, poisoning or reduction, said inlet distribution system being able to channel said two feed streams to any one or more of said reaction vessels or eliminate feed to any one or more reaction reactor vessels, said outlet distribution system ports the outlet stream from the on-duty reaction vessel to at least one monitor and simultaneously ports the outlet streams from the off-duty reaction vessels through a treat gas purge valve, wherein said inlet and outlet distribution systems include a means to control the on-duty reaction vessel's TOS in going from about 0% catalyst deactivation to about 90% catalyst deactivation based on a signal from said at least one monitor, and wherein said inlet and outlet distribution systems include a control means to modify the treat gas composition to the remaining one or more off-duty reaction vessels for pretreatment of catalyst prior to porting the hydrocarbon reactant to a new on-duty reaction vessel, previously an off-duty reaction vessel.
