Process for manufacturing a catalyst for hydrocarbon conversion consisting of a mordenite containing less than 0.5% by weight of sodium, having a molar ratio SiO2/Al2O3 from 10 to 100 and further containing at least one metal selected from cobalt, nickel, silver and palladium, wherein said metal in incorporated to a mordenite of the sodic form having a molar ratio SiO2/Al2O3 close to 10, the major portion of the sodium is eliminated, the resulting catalyst mass is dried from about 50 DEG to 150 DEG C. and then subjected to a first so-called dry calcination between 300 DEG and 700 DEG C., in the presence of a dry, inert or oxidizing gas containing less than 1% by volume of steam, and to a second so-called wet calcination between 250 DEG and 700 DEG C., in the presence of either steam or an inert or oxidizing gas containing at least 3% of steam. |
