1. A noble metal catalyst for hydro-regeneration of a deactivated ionic liquid catalyst containing a conjunct polymer, wherein the noble metal catalyst comprises a Group VIII noble metal hydrogenation component on a support having mesopores and macropores; wherein the noble metal catalyst has an average pore diameter of 27 to 1,000 nm (0.027 to 1 μm), a total pore volume of greater than 0.8 cc/g, and a macropore volume of 0.10 to 0.50 cc/g; wherein the mesopores have a diameter from 2 to 50 nm, and the macropores have a second diameter from greater than 50 to 5,000 nm. 2. The noble metal catalyst of claim 1, wherein the noble metal catalyst has an average pore diameter of from 27 to 800 nm (0.027 to 0.8 μm). 3. The noble metal catalyst of claim 1, wherein the noble metal catalyst has the total pore volume of from 0.85 to 1.5 cc/g. 4. The noble metal catalyst of claim 1, wherein the Group VIII noble metal hydrogenation component is selected from Pd, Pt, and combinations thereof. 5. The noble metal catalyst of claim 1, wherein an amount of the Group VIII noble metal hydrogenation component is in a range from 0.05 to 2.5 wt. % of a total weight of the noble metal catalyst. 6. The noble metal catalyst of claim 1, wherein the support is alumina. 7. The noble metal catalyst of claim 1, wherein the average pore diameter is from 28 to 800 nm. 8.
