CATALYST COMPOSITIONS AND PROCESSES FOR MAKING AND USING SAME
Catalyst compositions and processes for making and using same. The catalyst composition can include 0.001 wt% to 6 wt% of a Group 8-10 element disposed on a support, based on the weight of the support. The support can include Al and at least 0.5 wt% of a Group 2 element, based on the weight of the support. The catalyst composition can be free of Si or can contain < 0.5 wt% of Si, based on the weight of the support.
