Fig. 2. Catalytic behaviours of Zn–ZrO2 and Zn–ZrO2/SSZ-13–45H catalysts for the conversion of syngas at different temperatures. (a) Zn–ZrO2 (Zn/Zr = 1 : 16). (b) Zn–ZrO2/SSZ-13–45H. (c) CO2 selectivity. Reaction conditions: W(Zn–ZrO2) = 0.20 g; W(Zn–ZrO2/SSZ-13–45H) = 0.60 g; H2/CO = 2; P = 3 MPa; F = 30 mL min–1; time on stream, 10 h.
