METHOD OF PREPARATION OF NON-PYROPHORIC COPPER-ALUMINA CATALYSTS

摘要

Provided is a process for preparing a non-pyrophoric catalyst having about 2 to 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.
