(a) Products selectivity without CO₂, (b) CO conversion and CO₂ selectivity, (c) ASF behaviour for total C_n of the same catalyst showing a chain-lengthening probability independent of the H₂/CO pressure ratio. Reaction conditions: Co₄Mn₁K_0.1 catalyst 0.5 g, 220 °C and 40 bar. The same batch of catalyst was subjected to conversion at different H₂/CO ratios (sequential increase from 0.5 to 9 every 24 h). The total time on stream of the catalyst was 144 h. See also Supplementary Fig. 6 for long-term stability tests.
