Aromatization catalyst, preparation method, regeneration method thereof, and aromatization method

A preparation method for an aromatization catalyst, consisting of steps of:

• mixing a nano zeolite molecular sieve with a binder at a dry basis weight ratio of (1:9)˜(9:1) to obtain a catalyst precursor;
• the catalyst precursor is successively subjected to an ion exchange modification and a first modification treatment, then subjected to a hydrothermal treatment, and further subjected to active metal loading and a second modification treatment, to obtain the aromatization catalyst;
• wherein
• an exchange element used for the ion exchange modification is at least one alkali metal selected from Group IA of the Periodic Table of the Elements, with a loading amount of 0.1˜2 wt % based on a weight of the exchange element with respect to a weight of the catalyst precursor;
• a first modifying element used in the first modification treatment is at least one element selected from Group IA, Group VA, and lanthanide metals of the Periodic Table of the Elements, with a loading amount of 0.05˜10 wt % based on a weight of the first modifying element with respect to the weight of the catalyst precursor;
• the active metal is at least one element selected from Group VIIB, Group VIII, Group IB and Group IIB of the Periodic Table of the Elements, with a loading amount of 0.5˜25 wt % based on a weight of the active metal with respect to the weight of the catalyst precursor;
• a second modifying element used for the second modification treatment is at least one element selected from Group VA and the lanthanide metals of the Periodic Table of Elements, with a loading amount of 0.05˜10 wt % based on a weight of the second modifying element with respect to the weight of the catalyst precursor.
