a The effect of reaction temperature. b CO2 hydrogenation in the presence of toluene over ZZO & M-22; CO2 hydrogenation over ZZO, M-22, ZZO & M-22 and toluene disproportionation over M-22. c Influence of M-22-modified times by TEOS on the aromatics distribution and toluene conversion. d The Stability test. Standard reaction conditions: 3 MPa, 320 °C, GHSV of a mixture gas (CO2/H2/Ar = 24:72:4) = 12000 mL g−1 h−1, and WHSV of toluene = 1 h−1. When only toluene: 3.0 MPa, WHSV of toluene = 1 h−1, GHSV of mixture gas (CO2/H2/Ar = 24:72:4) = 12000 mL g−1 h−1. The color shadings represent the selectivity, and the red square represents the conversion.
