In our previous work, we reported the catalytic performance of 22 pellets of an industrial Pd-Ag/Al2O3 acetylene hydrogenation catalyst. For an ideal comparison to the industrial benchmark we therefore prepared 22 pellets of the [Pd(2-pymo)2]n/Al2O3 eggshell catalyst in the same cylindrical modification and a weight loading of 1.48 wt% of MOF with regard to the alumina support. These 22 catalyst pellets were then measured under the same feed composition #2 (Table ), pressure, volume flow and in the same reactor setup as the industrial benchmark in the previous work. The comparison (Figure ) shows a similar behavior of the two catalysts at 90 °C, with both at full conversion and an ethane make of 0.37 mol%. But at 80°C the ethane make of the [Pd(2pymo)2]n/Al2O3 catalyst is with 0.054 mol% significantly lower than the industrial Pd-Ag/Al2O3 catalyst with 0.144 mol% under comparable conversion. The ethane make of [Pd(2pymo)2]n/Al2O3 catalyst at lower temperatures is also better than the industrial benchmark but here the conversion of the industrial Pd-Ag/Al2O3 catalyst excels that of the presented catalyst. Also, the combined C4 selectivity of the industrial benchmark catalyst is lower over the temperature program. Overall, the [Pd(2pymo)2]n/Al2O3 catalyst shows a very similar catalytic performance compared to the industrial benchmark catalyst. Moreover, in its current form, a reduction of more than 62 % of ethane make at 80 °C with only 5.4 % less acetylene conversion is remarkable. This observation might indicate a pore size selectivity of the MOF catalysts as acetylene (van der Waals dimensions: 3.4 Å to 5.7 Å) is slender than ethylene (van der Waals dimensions: 4.3 Å to 4.8 Å) with a [Pd(2-pymo)2]n-MOF pore opening of 4.8 Å. As a follow-up to the benchmark experiment a long-time study of the catalyst performance at 70 °C under a volume flow of 62.7 L • h -1 of feed #2 (Table ) was carried out. The acetylene conversion, ethane make and the C4 selectivity were monitored over the course of 50 h as shown in Figure . The detailed formation of 1-butene, c-butene, t-butene and 1,3-butadiene was also tracked (Figure ). Over the total 50 h time-on-stream the [Pd(2-pymo)2]n/Al2O3 eggshell catalyst showed a very stable performance (Figure ). The acetylene conversion dropped only slightly from 47.5 % at the beginning to 44.9 % at the end. The ethane make remained low, with only a slight increase from 0.008 mol% to 0.010 mol%. The most significant observation was the reduction of the C4 selectivity from 18.7 % at the start to 14.6 % at the end of the 50 h period. The detailed analysis of the C4 species formation (Figure ) revealed a reduction of 1-butene, c-butene and t-butene selectivity over the course of the experiment. Only the formation of 1,3-butadiene remained rather constant. In summary, the catalytic performance of the [Pd(2pymo)2]n/Al2O3 eggshell catalyst at a total time on stream of 60 h remained competitive to the industrially applied benchmark catalyst.
