Claim Text:
1. A sulfur-tolerant and carbon-resistant noble-metal based trimetallic catalyst of the formula M1(x)M2(y)M3(z) on a metal oxide doped stabilized gamma alumina support where 0.5%≦x≦5%, 2%≦y≦20% and 2%≦z≦20% where all amounts of x, y and z are based on total weight of the catalyst including the support, and where M1 is selected from the group consisting of Rh, Ru, and Pt, M2 and M3 are different and each is selected from the group consisting of Ni, Co, Fe, Mo, Cu, and Zn and where the metal oxide is any one or more of Ce, Zr, Ga or Y oxide and where the amount of metal oxide in the doped support is more than 10 wt. % to about 70 wt. % based on total weight of the doped support.
