Description

technical field

[0001] The invention relates to an alkane aromatization catalyst and a preparation method thereof, in particular to a nano-aromatization catalyst with molecular sieve as a carrier and a preparation method thereof, which can be used for C 3 ~C 8 Alkane dehydroaromatization process. Background technique

[0002] C 3 ~C 8 Aromatization of alkanes can increase the utilization value of alkanes, and its aromatized products such as benzene, toluene, xylene, naphthalene, etc. are important raw materials for organic chemical and fine organic chemical production, which can be used directly or indirectly for solvents, rubber, unsaturated The production of polyester and pharmaceutical intermediates has a wide range of uses. Currently, the most studied catalysts for alkane aromatization include transition metals or noble metals as active components, and various types of additives are added to obtain high-performance catalysts.

[0003] The aromatization catalysts dis...
