I. Product introduction

4Cu + O₂→2Cu₂O

2Cu₂O + O₂→4CuO

AS-CU40 is extruded molding by adding binder to metal oxide. Oxygen removal is achieved by the reduction of high-valence metal oxides to low-valence metal oxides, which is achieved by the oxidation of the catalyst into copper oxide.

4Cu + O2→2Cu2O

2Cu2O + O2→4CuO

II. Technical introduction

AS-CU40 catalyst is applicable to oxygen removal in propylene, ethylene and inert gas. It is featured in good low temperature activity, high conversion rate, strong stability, high selectivity and long service life.
