T:室温
P:1bar
触媒体積:85ml
プロピレン流:150NL×hrs−1
GHSV:1.765hrs−1
CO濃度:100ppm
還元レベルRに応じた吸着組成物のCO取り込み容量を次のようにして測定した:
還元レベルに応じたCO取り込み容量の測定のために、異なる還元レベルの数種の吸着組成物を特別に調製し、それぞれを上述したように試験した。
吸着組成物の最大のCO取り込み容量に達するとすぐに、COのブレークスルーが認められた。この時点でガス供給流を停止し、触媒を再生するために200℃に加熱した。効率的に再生するための最低温度は190℃であった。180℃未満では、有意な再生が認められなかった。再生は工業用窒素を用いて200〜250℃で行った。
還元レベルが75%の未処理の触媒は、第一サイクルでは吸着組成物1リットル当たり0.08NL COしかCO取り込み容量を示さなかった。同じ触媒をまず30℃で1時間、プロピレン50%及びN250%の混合物を用いて1.75hrs−1のGHSVで処理し、次いで、250℃において3時間工業的に純粋な窒素を用いて熱すると、CO取り込み容量は吸着組成物1リットル当たり0.55NL COまで上昇した。
再生を工業的に純粋な窒素を用いて行った活性化段階の後、各吸着工程の後に1500ppmの酸素を含む窒素流を用いて再生を行った。この間の温度は200℃であり、GHSVは500hrs−1であった。合計で3時間にわたって2.3NLの酸素を触媒1リットル当たりに供給した。
