Figure 4. Catalytic performance of selective 1,3-butadiene hydrogenation over the series of Pd/CeO2 catalysts. (A) 1,3-butadiene conversion, (B) butenes selectivity as a function of reaction temperature, durability tests over Pd/CeO2-H600 at 110 °C with WHSV of (C) 60,000 and (D)120,000 mL/gcat/h. Reaction conditions: 2 vol.% 1,3-butadiene, 6 vol.% H2, He balanced. WHSV: Weight hourly space velocity.
