Figure 1

On stream catalytic performance of the 1-butene isomerization catalyst 2 in solid/gas flow, 298 K, 1 atm. Data plotted are total 2-butenes (GC conversion). 1-Butene (2%)/isobutene co-feed (15% relative to 1-butene)/balance N2, unless otherwise stated. (A) 2 6 mg with (○) and without (□) isobutene co-feed. (B) Recycling of pre-catalyst 2 by periodic addition of H2 after 3 h (×2). (C) cis/trans ratios on flow using 2 (6 mg). (D) Comparison of 2 and 7 (H2 activation) under multiple batch-recharges with 1–butene (298 K, 1 atm = 81 μmol, 2 mg of catalyst ∼1.8 μmol).
