Abstract
Long-duration tests for catalyst B have been performed, both out-of-cell (at BG for 2500 hrs) and in-cell (at ECN for 5400 hrs). Any significant degradation of the catalyst was not shown. BG studied the distribution of potassium in post-test alumina-based samples. First the potassium was distributed homogeneously throughout the catalyst. From 100 hours onwards, however, K seemed to be preferentially located on the catalyst support. At CKKO, the stability of several catalysts, prepared by deposition precipitation of commercially available supports, has been investigated and compared with catalysts B and H. CNR has performed two bench-cell experiments to investigate the effect of a Ni net on the alkali uptake by the catalyst. ECN performed a bench-cell experiment using a catalyst sample which has been tested for 100 hours in the BG test reactor. The purpose was to compare the test conditions of the BG reactor and the ECN bench-cell facility regarding the catalyst deactivation. Finally, two stack experiments were performed at ECN. One was a triple-cell experiment, aimed at testing the suitability of modified FLEXSEP separator plates for the 1 kW stack test. Since the results were positive, these separator plates were also used in the subsequent 1 kW stack test.
