FIELD: chemistry.SUBSTANCE: present invention relates to an in-situ method for preparing a catalyst for production of at least one of toluene, para-xylene and lower olefins, as well as a reaction process for the production of at least one of toluene, para-xylene and lower olefins, and relates to the field chemical technology. Described is a method of in-situ preparation of a catalyst in which a modifier is brought into contact with a zeolite molecular sieve in a reactor for in-situ preparation of a catalyst for the production of para-xylene, toluene and / or lower olefins from a raw material containing methanol and / or dimethyl ether; and the reactor is a reactor for producing para-xylene, toluene and / or lower olefins from a raw material containing methanol and / or dimethyl ether. The modifier contains at least one of the following modifiers: Modifier I: a phosphorus-containing reagent and a silylating reagent; Modifier II: silylating agent; Modifier III: silylating agent and steam; Modifier IV: phosphorus-containing reagent, silylating reagent and water vapor. Also described is a method for carrying out the following reaction, in which a raw material containing methanol and / or dimethyl ether and toluene is brought into contact with a catalyst. Also disclosed is a method for carrying out the following reaction in which a raw material containing methanol and / or dimethyl ether and benzene is brought into contact with the catalyst.EFFECT: development of an easy-to-operate method of in-line catalyst production for production of para-xylene or lower olefins and the joint production of para-xylene.21 cl, 41 tbl, 45 ex, 6 dwg Настоящее изобретение относится к способу in-situ получения катализатора для получения по меньшей мере одного из толуола, пара-ксилола и низших олефинов, а также к процессу реакции получения по меньшей мере одного из толуола, пара-ксилола и низших олефинов, и относится к области химической технологии.
