The present invention uses water glass, silica sol and aluminium sulfate as raw materials. In the presence of organic amine or quaternary ammonium salt or alkali, the above-mentioned raw materials are mixed with alkali, salt, water and seed crystal according to a certain mole ratio, and after going through the processes of changing temp., crystallizing, separating, washing with water and drying, the 10-500nm superfine particles of Pentasil type ZSM-5 and ZSM-11 zeolites are obtained. They possess high reactive activity, stability and resistance to carbon deposition inactivation, can be used for preparing catalysts for alkylation, dismutation and transalkylation of benzene, methylbenzene and ethylbenzene, the reaction of removing thiofuran from benzene and desulfurization of gasoline.
