High selective and stable performance of catalytic aromatization of alcohols and ethers over La/Zn/HZSM-5 catalysts
E-mail:,
The catalytic conversions of methanol, ethanol, dimethyl ether and diethyl ether to aromatic hydrocarbons (especially benzene, toluene and xylene) were achieved over 0.8%Zn/0.6%La/HZSM-5 catalyst with a BTX selectivity as high as over 50% at reaction conditions of 710 K, WHSV 0.8 h^(-1). The selectivity of BTX hydrocarbons in methanol aromatization reaction could remain 35% in 40 h.
