The invention discloses a low carbon hydrocarbon aromatization method, which comprises that: under the low carbon hydrocarbon aromatization operating condition, a low carbon hydrocarbon material passes through reaction areas at least containing two aromatization catalysts, wherein the low carbon hydrocarbon material passes through a reaction area containing an HZSM-5 molecular sieve aromatizationcatalyst first and then passes through a reaction area containing a hydrogen mordenite aromatization catalyst. The low carbon hydrocarbon aromatization is carried out by using different aromatizationcatalysts, and on the premise of not reducing the yield of aromatic hydrocarbon, the content of benzene and dimethylbenzene with high utilization value in reaction products can be obviously improved,the content of methylbenzene with low utilization value is reduced and the economical efficiency of a low carbon hydrocarbon aromatization process is improved.
