Feed composition according to Gislason et al. Hock et al. C2H4 The experiments were carried out over a temperature range from 30-90 °C, which represents the industrially relevant range. Starting at 30 °C in steps of 10 K, each temperature was analyzed over the course of 70 minutes reaching steady-state conditions. The temperature was then increased by steps of 10 K at a rate of 1 K • min -1 and the new conditions were monitored. The resulting acetylene conversion, ethane selectivity and C4 selectivity of 250 mg [Pd(2-pymo)2]n as synthesized are shown in Figure . The numerical measurement data alongside the calculation and detailed information on 1 -butene, c-butene, t-butene and 1,3-butadiene formation is shown in the SI. ]n as synthesized measured in a continuously operated fixed-bed reactor laboratory plant using feed #1 (Table ) with a volume flow of 62.7 L • h -1 (Table ). The selectivity of 1-butene, c-butene, t-butene and 1,3-butadiene is summed up.
