この還元レベルは、本発明の吸着組成物中に含まれる銅の酸化物含量の尺度である。この還元レベルは、次式により、全体の銅の中に含まれる還元銅の平均物質含有率、即ち酸化状態が0(Cu0)または1(Cu1)である銅の平均物質含有率として求められる。
2Cu+O2→2CuO
または
2Cu2O+O2→4CuO
Mは、関係する成分CuまたはCuOのモル質量であり、
yCuOは、完全酸化された触媒中の酸化物の合計に対するCuOの質量比率であり、
Δmは、完全酸化による相対的な質量増(%)である。
吸着組成物の%含量の合計は100質量%である。
以下の加工工程をその順で含む:
a)吸収組成物の成分及び/又はこれらの可溶性出発化合物の溶液の製造;
b)塩基の添加によるこの溶液から固体の析出;
c)この固体の分離と乾燥;
d)必要に応じてこの固体の焼成;
e)この固体の成形物への成形;
f)必要に応じてこの成形物の焼成;
ただし、上記二つの焼成工程d)またはf)の少なくとも一つが実施され、工程f)の後、あるいはこれと同時に、工程

T:室温
p:1bar
触媒体積:85ml
プロピレン流:150NL・h−1
GHSV:1.765h−1
CO濃度:100ppm
吸着組成物の最大CO吸収容量に至ると、直ちにCOの破過が観察された。この時点でガス供給を停止し、触媒を再生のために200℃に加熱した。効果的な再生に必要な最低温度は190℃であった。180℃未満では、十分な再生が認められなかった。この再生は、工業用窒素を用いて200〜250℃で行った。
工業的に純粋な窒素で再生を行う活性化相の後で、各吸着工程の後で、1500ppmの酸素を含む窒素流を用いて再生を行った。この際の温度は200℃であり、GHSVは500h−1であった。3時間かけて、1リットルの触媒あたり2.3NLの酸素を供給した。
