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.

Cyclic metal deactivation unit design for FCC catalyst deactivation

The present invention provides a metal passivator/trap comprising a rare earth oxide dispersed on a matrix containing a calcined hydrous kaolin.

Rare earth-containing attrition resistant vanadium trap for catalytic cracking catalyst

A phosphorus modification of an FCC catalyst is provided by reducing the sodium content of the as formed catalyst, a first treatment with a phosphate solution, a second ammonium exchange to further reduce the sodium content of the phosphorus solution treated catalyst and a second treatment with a phosphate solution.

Phosphorus modified cracking catalysts with enhanced activity and hydrothermal stability

A composition for controlling NOemissions during FCC processes comprises (i) an acidic oxide support, (ii) cerium oxide, (iii) a lanthanide oxide other than ceria such as praseodymium oxide, and (iv), optionally, an oxide of a metal from Groups Ib and IIb such as copper, silver and zinc.
