Abstract
The present invention provides catalyst compositions useful for transamination reactions. The catalyst compositions have a catalyst support that includes transitional alumina, use a low metal loading (for example, less than 25 wt. %), and do not require the presence of rhenium. The catalyst compositions are able to advantageously promote transamination of a reactant product (such as the transamination of EDA to DETA) with excellent activity and selectivity, and similar to transaminations promoted using a precious metal-containing catalyst.
Claims20
A catalyst composition comprising:
- (a) a support portion comprising an acidic mixed metal oxide comprising a transitional alumina and a second metal oxide, wherein the second metal oxide has a weight percentage that is less than the weight percentage of alumina, and
- (b) a catalyst portion comprising one or more metals selected from the group consisting of cobalt, nickel, and copper,
- wherein there is no, or less than 0.01 wt. % rhenium in the catalyst composition, and the catalyst portion is 25 wt. % or less of the catalyst composition.
