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.
Claims8
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.
