Coupling Conversion of CO₂ and High‐Carbon Alkane to CO and Gasoline

Abstract Catalytic conversion of CO 2 to valuable products is a promising way to reduce anthropogenic CO 2 emission. Herein, a strategy for coupling conversion of CO 2 and high‐carbon alkane to CO and gasoline is developed, which is a feasible choice for the combination of CO 2 recycling and petroleum refining. The CO 2 conversion reaches 2.6% under mild condition (270 °C), and the selectivity of gasoline in the cracking products exceeds 70 wt%. Additionally, the introduction of CO 2 improves the selectivity of aromatic hydrocarbons and increases the octane number of gasoline. Mechanism studies indicate that synergistic effect between Brønsted acid centers and Ni sites on the Beta zeolite supported Ni (20 wt%) catalyst (20Ni/β) plays the key role in alkane cracking and CO 2 reduction. Notably, 13 CO 2 isotopic experiments show that the hydrogen produced during the aromatization can be captured by CO 2 , inhibiting undesired hydrogen transfer pathways and enhanced the yield of aromatics, while CO 2 is converted into valuable CO.
