Effect of reaction conditions [(A) reaction temperature, (B) total pressure, (C) CO2/H2 ratio, and (D) reaction time] on the CO2 hydrogenation using 20 mg of Co6/MnOx and 1 mL of squalane. Other conditions: (A) 4 MPa of CO2 and 4 MPa of H2, 15 h; (B) PCO2/PH2 = 1, 200 °C, 15 h; (C) initial pressure 8 MPa, 200 °C, 15 h; and (D) 4 MPa of CO2 and 4 MPa of H2, 200 °C. Symbols: triangle, C5+ selectivity; circle, C1–4 selectivity; square, CO selectivity; star, activity; diamond, CO2 consumption.
