“…Catalyst poisoning experiments were carried out in a reactor similar to the one described by Vogel et al (1988). A small boat containing As2Os powder was mounted in the furnace section upstream of a nine-channel monolith piece.…”

“…Figure 13 shows the results of this comparison. Chen and Yang [118] used smaller amounts of arsenious oxide in their deactivation experiments than Vogel et al [117]. They observed a value of 0.47 for the ratio of k : ko for an arsenic level of about 0.12 ng g-' .…”

“…Moreover, it was established that the largest contribution to the decrease of k : ko occurred in the first 1000 h of operation. Most of the arsenic was [117]. As205 vapor deposited on the catalyst surface forms an inactive monolayer.…”
