ABSTRACT OF THE DISCLOSURE REJUVENATION PROCESS FOR CATALYST CARRIER PARTICLES AND FOR CATALYSTS A process for rejuvenating catalyst carrier particles comprising alumina, having pores plugged or fouled with metal sulfide contaminant as a result of hydrotreating a hydrocarbon feed containing organometallic compounds and sulfur-containing compounds using a catalyst for which the particles are the carrier for catalytic components, by the process steps including leaching with at least 5 weight percent aqueous nitric acid and oxidizing residual oxidizable matter from the leached particles by contacting them at a temperature below their sintering temperature with molecular oxygen. A rejuvenated catalyst is prepared from the rejuvenated carrier particles by restoring the catalytic component by impregnating the leached carrier particles with a suitable solution of the catalytic component, or a precursor thereof, and calcining the resulting particles below their sintering temperature.
