N2 - In recent years, the direct and efficient conversion of CO2 to light aromatics (BTX: benzene, toluene and xylene) has attracted wide attention. It not only reduces the CO2 concentration in the atmosphere but also provides a promising non-petroleum technology to produce BTX. Herein, a composite ZrCr-C/ZSM-5 catalyst was developed for CO2 to BTX. Different with conventional SiO2 modification method, the HZSM-5 zeolite was modified by amorphous carbon (C) through a facile modified impregnation method. The amorphous C could enter the internal channel of HZSM-5 zeolite and poison partial acid sites. In CO2 to BTX reaction, after introducing 1.45 wt% C on HZSM-5 zeolite, BTX selectivity increased from 36.2% to 45.4%. In addition, the ZrCr-1.45 C/ZSM-5 catalyst exhibited 46.9% BTX selectivity with 13.5% CO2 conversion, under 5.0 MPa, 360 °C and 4800 mL/gcat/h. This work not only paves a new strategy to modify HZSM-5 zeolite but also provides an efficient composite catalyst for direct conversion of CO2 to BTX.
