Method of preparation of non-pyrophoric copper-alumina catalysts

Provided is a process for preparing a non-pyrophoric catalyst having about 2 to 20 wt. % of a copper component, wherein at least 50 wt. % of the copper component is in the form of a copper oxide, aluminum oxide-spinel. The catalyst can be prepared by forming a mixture of a copper precursor and an al...

Beschreibung
Zusammenfassung:	Provided is a process for preparing a non-pyrophoric catalyst having about 2 to 20 wt. % of a copper component, wherein at least 50 wt. % of the copper component is in the form of a copper oxide, aluminum oxide-spinel. The catalyst can be prepared by forming a mixture of a copper precursor and an alumina precursor, coextruding the mixture, drying the coextrudate and calcining the dried coextrudate at a temperature of at least 600° C. In other aspects, the invention also relates to processes for the activation of copper-based catalysts and for the regeneration of deactivated copper-based catalysts.
