Abstract

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

What is claimed is:

1. A cyclic metals deactivation system unit for production of equilibrium catalyst materials, the cyclic metals deactivation system unit comprising:
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;
wherein the cracker vessel is maintained at a first temperature throughout the cracking and the stripping of the catalyst material; and
wherein the regenerator vessel is maintained at a second temperature throughout the regeneration and steam deactivation of the catalyst material.

2. The cyclic metals deactivation system unit 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 cyclic metals deactivation system unit of claim 1 , wherein the cracker vessel comprises a first porous plate disposed within a lower region of the cracker vessel.

4. The cyclic metals deactivation system unit 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 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 cyclic metals deactivation system unit of claim 1 , wherein the regenerator vessel comprises a second porous plate disposed within a lower region of the regenerator vessel.

6. The cyclic metals deactivation system unit 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 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 cyclic metals deactivation system unit 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 cyclic metals deactivation system unit of claim 6 , wherein the second gas inlet is fluidly connected to a second gas pipe within the second gas redistribution region of the regenerator vessel, the second gas pipe comprising a coiled configuration for preheating incoming gas within the second gas redistribution region of the regenerator vessel.

9. The cyclic metals deactivation system unit of claim 1 further comprising an age distribution vessel in fluid communication with the regenerator vessel, the age distribution vessel configured for distributing the catalyst material based on an age of the catalyst material.

10. The cyclic metals deactivation system unit of claim 7 , wherein the cracker vessel, regenerator vessel, and an age distribution vessel are in fluid communication with one another via a pneumatic valve system.

11. The cyclic metals deactivation system unit of claim 10 , wherein the pneumatic valve system includes a first dip tube in the cracker vessel, a second dip tube in the regenerator vessel, and a third dip tube in the age distribution vessel.

12. The cyclic metals deactivation system unit of claim 9 , wherein each of the cracker vessel, regenerator vessel, and age distribution vessel comprise a temperature maintenance device, wherein the temperature maintenance device maintains a predetermined process temperature in each respective vessel.
