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.

Method for preparing a catalyst support

The present invention relates to a process for deparaffinning a middle distillate feedstock, to convert, in good yield, feedstocks having high pour points into at least one cut having an improved pour point. Said process is performed with at least one catalyst comprising at least one hydro-dehydrogenating phase containing at least one metal from group VIB and at least one metal from group VIII of the Periodic Table of the Elements, and a support comprising at least one IZM-2 zeolite, a zeolite of WI framework type code and at least one binder.
