Abstract
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.
