As revealed by TEM and CO chemisorption results, smaller Pd particle sizes with more uniform particle size distribution were obtained on Pd-toluene catalysts. Reduction at 500°C resulted in sintering of Pd particles with Pd-water showing higher degree of metal sintering than Pd-toluene. Sintering of Pd particles may result in low-index surfaces which promoted butane formation and lowered 1-butene selectivity. While Pd dispersion and/or Pd particle size strongly affected 1,3-butadiene hydrogenation rate and 1-butene selectivity, the selectivity to 2-butenes was quite similar at 47-55% for all the catalysts under various reaction conditions.
