The invention relates to a method for preparing aromatic hydrocarbons through catalytic conversion of
methanol. A purpose of the present invention is mainly to solve the problems of low
aromatic hydrocarbon yield and serious hydrothermal deactivation of the catalyst in the prior art. According to the technical scheme, a
methanol raw material enters a
fluidized bed reactor, and is subjected to a
contact reaction with a modified ZSM-5 catalyst to obtain an
aromatic hydrocarbon-containing product and a spent catalyst; the steam stripped spent catalyst enters a riser regenerator, and contacts a regeneration medium I, and
charring is performed at a temperature of 500-600 DEG C; the outlet of the riser regenerator is connected to at least a set of closed
cyclone separators; the semi-regeneratedcatalyst separated by the closed
cyclone separators enter a
fluidized bed regenerator, and contacts a regeneration medium II, and
charring is continuously performed at a temperature of 630-700 DEG C;the regenerated catalyst enters a degassing tank; and the degassed product returns to the
fluidized bed regenerator. With the technical scheme, the problems in the prior art are well solved. The method of the present invention can be used in the industrial production of aromatic hydrocarbons.
