EFFECT OF VANADIUM ON THE DEACTIVATION OF FCC CATALYSTS
This work provides concrete evidence that vanadium causes the destruction of the zeolite in the FCC catalysts by a mechanism of acid attack or solid-solid transformation, as well as additional dealumination of the zeolite framework in the presence of steam and at high temperature. While these effect...
