Abstract
The invention provides a catalyst composition composed of a support portion and a catalyst portion. The support portion includes an acidic mixed metal oxide including a transitional alumina and a second metal oxide. The transitional alumina can comprise delta or theta alumina, in combination with other transitional phases, or an alpha or gamma alumina. The second metal oxide has a weight percentage that is less than the weight percentage of alumina. The catalyst portion is 25 weight percent or less of the catalyst composition and is composed of nickel and rhenium. The catalyst portion includes nickel in an amount in the range of 2 to 20 weight percent, based upon total catalyst composition weight, and there is no boron in the catalyst portion.
