- Abstract
ZrO2 and catalysts were prepared by a co-precipitate method and coupled with a HZSM-5 zeolite catalyst through a mechanical mixing method; these were applied to the direct synthesis of aromatic hydrocarbons from syngas through an oxygen-containing intermediate route. The physical and chemical properties of the catalysts were characterized by XRD, H2-TPR, CO2-TPD, and SEM methods. The comparative catalytic effects of ZrO2 and MgZrOx catalysts were discussed under different reaction conditions. The reaction results showed that the addition of Mg to a ZrO2 catalyst reduced the selectivity of CO2 by inhibiting the water–gas conversion reaction, and increased the selectivity of aromatics and the proportion of BTX in aromatic products.
