Abstract: A method for dehydroaromatization of methane, comprising: introducing methane and carbon dioxide into an aromatization reactor; converting a portion of the methane to aromatic hydrocarbons in the presence of a dehydroaromatization catalyst at a temperature of 700 to 850° C.; regenerating the dehydroaromatization catalyst with hydrogen at a regeneration temperature of 700 to 800° C.; and repeating the introducing, the converting and the regenerating; wherein after every 2 to 5 cycles of the regenerating, increasing the regeneration temperature by 5 to 15° C.
