英文摘要: Benzene as an important raw material for production of industrial chemicals is generally synthesized from petroleum and coal tar. Here, we realized the synthesis of benzene from greenhouse CO2 and H-2 with two connected reactors by a tandem catalysis reaction comprising CO2 methanation and CH4 aromatization. The Ni/SiO2 catalyst loaded in the first reactor was used to convert CO2 to CH4, and the formed CH4 was sequentially converted to benzene on the Mo/HZSM-5 catalyst in the second reactor. The benzene formation rate reaches 0.68 mu molg(-1) min(-1) accompanied by a high CO2 conversion of 92%. This concept will provide a new pathway for the direct synthesis of benzene and CO2 utilization.
