Abstract
Official abstract text for this publication.
A cyclic metals deactivation system unit for the production of equilibrium catalyst materials including a cracker vessel configured for cracking and stripping a catalyst material; and a regenerator vessel in fluid communication with the cracker vessel, the regenerator vessel configured for regeneration and steam deactivation of the catalyst material.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of catalyst deactivation, the method comprising: cracking, by a cracker vessel, a catalyst; regenerating, by a regenerator vessel, the catalyst; distributing, by an age distribution vessel, the catalyst based at least in part on an age of the catalyst; and transporting, by one or more dip tubes, the catalyst between the cracker vessel, regenerator vessel, and the age distribution vessel to deactivate the catalyst. 2. The method of claim 1 , wherein the cracker vessel and the regenerator vessel are in fluid communication with one another via a pneumatic valve system including a first dip tube in the cracker vessel, and a second dip tube in the regenerator vessel. 3. The method of claim 1 , wherein the cracker vessel comprises a first porous plate disposed within a lower region of the cracker vessel. 4. The method of claim 3 , wherein the first porous plate defines a first gas distribution region including an inner bottom surface of the cracker vessel and a first gas inlet is disposed within the first gas distribution region, wherein the first gas inlet is configured to introduce a first gas source to the cracker vessel. 5. The method of claim 1 , wherein the regenerator vessel comprises a second porous plate disposed within a lower region of the regenerator vessel. 6. The method of claim 5 , wherein the second porous plate defines a second gas distribution region including an inner bottom surface of the regenerator vessel and a second gas inlet is disposed within the second gas distribution region, wherein the second gas inlet is configured to introduce a second gas source to the regenerator vessel. 7. The method of claim 4 , wherein the first gas inlet is fluidly connected to a first gas pipe within the first gas distribution region of the cracker vessel, the first gas pipe comprising a coiled configuration for preheating incoming gas within the first gas distribution region of the cracker vessel. 8. The method of claim 6 , wherein the second gas inlet is fluidly connected to a second gas pipe within the second gas distribution region of the regenerator vessel, the second gas pipe comprising a coiled configuration for preheating incoming gas within the second gas distribution region of the regenerator vessel.
