The invention disclose a methanol aromatization technology which includes following steps: 1) feeding methanol into a tube side of a reactor to enable the methanol to contact with a tube-side catalyst with an operation temperature being 400-450 DEG C and an operation pressure being 0.1-5 Mpa, wherein a liquid space velocity of the raw material methanol is 0.5-7.0 h<-1>; 2) feeding a reaction product out of the tube side into a shell side of the reactor to enable the reaction product to contact with a shell-side catalyst with an operation temperature being 330-380 DEG C, an operation pressure being 0.1-3.5 Mpa and an operation space velocity being 0.4-4.0 h<-1>; performing a catalytic convention reaction in the shell side to obtain C5+ hydrocarbon liquid products and performing a rectification separation process to obtain aromatic hydrocarbons and non-aromatic hydrocarbons; and performing a separation process to gas products in shell-side products, wherein low-carbon olefins are fed back to the shell side of the reactor for being subjected to a reaction continuously. By means of the technology, utilization of the methanol can be increased, a complex reaction can be simplified, selectivity of the low-carbon olefins is enhanced and generation of dry gas and liquefied gas can be reduced.
