a, Overall catalyst productivity of 1.1Co-S-1 and other PDH catalysts reported by Motagamwala et al.29 (the numbers in parentheses correspond to the row numbers in Supplementary Table 7). b, On-stream profiles of yield of C3H6 (Y(C3H6)) and STY(C3H6) over 1.1Co-S-1 in a series of 120 PDH/regeneration cycles performed at 500 °C (red) and 525 °C (green). Reaction conditions: T = 500–525 °C, C3H8/N2 = 1:4 and WHSV(C3H8) = 4.7 h−1. c, On-stream profiles of X(C3H8) and S(C3H6) over 1.1Co-S-1 in a series of 20 PDH/regeneration cycles performed at 500 and 550 °C (10 cycles each). Reaction conditions: C3H8/N2 = 2:3 and WHSV(C3H8) = 4.7 and 9.4 h−1 at 500 and 550 °C, respectively.
