摘要

The catalytic conversions of CH₃Br into aromatics over HZSM-5, CuO/HZSM-5, ZnO/HZSM-5 and CuO-ZnO/HZSM-5 were investigated to study the synergistic effect of CuO and ZnO. The results showed that the yield of aromatics decreased in the order of 2%CuO-3%ZnO/HZSM-5 (27.4%) > 5%CuO/HZSM-5 (19.3%) > HZSM-5 (14.4%) > 5%ZnO/HZSM-5 (6.0%) at 360 °C under the same condition, and the bimetallic 2%CuO-3%ZnO/HZSM-5 gave 33.0% aromatic yield at 380 °C. The addition of ZnO promoted the catalytic activity of CuO in CH₃Br aromatization to aromatics. The higher strong acidity significantly improved the hydrogen-transfer and aromatization reaction, increasing the yield of aromatics.
