PROCESS FOR PREPARATION OF CATALYST USING AT LEAST ONE RAPID DRYING STAGE AND AT LEAST ONE FLUIDISED BED DRYING STAGE AND USE THEREOF FOR FISCHER-TROPSCH SYNTHESIS

摘要

PROBLEM TO BE SOLVED: To provide a process for preparing a catalyst, having an activity and selectivity maintained in respect of a C5compound in enhanced water thermal resistivity and Fischer-Tropsch synthesis.SOLUTION: A process prepares a catalyst comprising an activation phase containing at least one metal from group VIII and an oxide support. The process comprises a stabilization stage of the oxide support, and the stage comprises an impregnation stage of the oxide support, a rapid drying stage, a calcination stage of impregnated and dried oxide support, the stabilization stage being followed at least once by the impregnation stage of stabilized oxide support, the drying stage of stabilized and impregnated oxide support operating in a fluidized bed in the presence of a gas, the support being subjected to a temperature rise ramp of between 0.5-5°C/min to attain a temperature of between 50-170°C, the residence time of the support once the drying temperature is reached being between 20-180 min, and the calcination stage of the dried impregnated stabilized oxide support.
