The Direct Synthesis of Aromatic Hydrocarbons from Syngas over Bifunctional MgZrOx/HZSM-5 Catalysts

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