A method for producing an aromatic hydrocarbon with an oxygenate as raw material, includes: i) reacting an oxygenate in at least one aromatization reactor to obtain an aromatization reaction product; ii) separating the aromatization reaction product to obtain a gas phase hydrocarbons flow X and a liquid phase hydrocarbons flow Y; iii) after removing gas and/or a part of the oxygenate from the gas phase hydrocarbons flow X, a hydrocarbons flow Xcontaining a non-aromatic hydrocarbon is obtained; or after removing gas and/or a part of the oxygenate from the gas phase hydrocarbons flow X, a reaction is conducted in another aromatization reactor and a separation is conducted to obtain a flow Xcontaining a non-aromatic hydrocarbon and a flow Xcontaining an aromatic hydrocarbon. The flows are further treated.

Method for producing an aromatic hydrocarbon with an oxygenate as raw material

The present invention relates to a catalyst for the conversion of methanol to aromatics and the preparation of the same. The catalyst comprising 85 to 99 parts by weight of a ZSM-5 zeolite, 0.1 to 15 parts by weight of element M1, which is at least one selected from the group consisted of Ag, Zn and Ga, and 0 to 5 parts by weight of element M2, which is at least one selected from the group consisted of Mo, Cu, La, P, Ce and Co, wherein the total specific surface area of the catalyst ranges from 350 to 500 m/g, and the micropore specific surface area ranges from 200 to 350 m/g. The catalyst has high total specific surface area, micropore specific surface area and micropore volume. Good catalytic activity can be shown from the results of the reaction of aromatics preparation from methanol using the catalyst provided by the present invention.
