Production of syngas from CO 2 via reverse water gas shift reaction using a Pt impregnated ZnO–Al 2 O 3 catalyst: life cycle analysis

The novel 1 wt% Pt-loaded ZnO–Al 2 O 3 catalyst achieved 34.8% CO 2 conversion and 99.4% CO selectivity at 400 °C, 20 bar, and 3111 h −1 using a fixed-bed reactor. The process showed a global warming potential of 3.09 × 10 4 kg CO 2 eq. via an LCA study.
