Abstract
A process for preparing a powder support containing alumina and silica or their derivatives for a catalyst of a Fischer-Tropsch type reaction, including stage (a) of preparing a first reactant containing an alumina compound or precursor including a reaction for peptization of an alumina compound or precursor in the presence of an acid, to form solid particles in suspension, stage (b) of preparing a second reactant based on silicic acid and/or on a compound or precursor of silicic acid, including a controlled aging treatment of the silicic acid targeted at its polymerization up to a degree of conversion of the silicic acid of at most 70%, stage (c) of mixing the two reactants in a mixer, and the pH of the first reactant is adjusted to a value not exceeding a given maximum pH threshold.
