The invention discloses a preparation method of an FCC gasoline desulfurization agent composition. The catalyst is prepared by the following steps of mixing and stirring water, a binding agent, an aluminum source, clay, a molecular sieve and zinc aluminate gahnite so as to form slurry, and then spraying drying so as to obtain the catalyst. The catalyst has an excellent function of reducing the sulfur content of gasoline, is relatively large in pore volume and smooth in duct, and is beneficial to the dispersion of a sulfide; as an active center, zinc aluminate gahnite can adsorb the sulfide of L alkali character, and is difficult to lose, and is better in stability when compared with zinc oxide. The catalyst can be doped with a conventional FCC catalyst, and also can be independently applied to the catalytic cracking technological process.
