Figure 4. Phenylacetylene hydrogenation reaction rates as a function of H2 (red □: 0.02%Pd-Y/C; green ■: 0.02%Pd-Lu/C) (0.5-50 kPa H2, 0.3 kPa C8H6, 2.784 kPa C6H12, balance with Ar, WHSV = 2,162 h-1) and C8H6 pressures (black ○: 0.02%Pd-Y/C; blue ●: 0.02%Pd-Lu/C) (30 kPa H2, 0.1-0.8 kPa C8H6, 2.784 kPa C6H12, balance with Ar, WHSV = 2,162 h-1) at (A) 363 K and (B) 373 K; (C) Apparent activation energies for phenylacetylene selective hydrogenation over 0.02%Pd-Y/C (black ○), 0.02%Pd-Lu/C (red □) and 0.02%Pd/C (blue △) catalysts. Reaction conditions: 30 kPa H2, 0.3 kPa C8H6, 2.784 kPa C6H12, balance with Ar, WHSV = 2,162 h-1. WHSV: Weight hourly space velocity.
