Abstract
Preparation of a catalyst comprising at least one metal from group VIII said process comprising stabilization of an oxide support, by impregnation of said oxide support, rapid drying, calcination of impregnated and dried oxide support, stabilization stage being followed at least once by impregnation of stabilized oxide support, drying of stabilized and impregnated oxide support operating in a fluidized bed in the presence of a gas, said support being subjected to a temperature rise ramp of between 0.5 and 5° C/min to attain a temperature of between 50 and 170° C, the residence time of said support once the drying temperature is reached being between 20 and 180 min, and calcination of said dried impregnated stabilized oxide support.
