Claim Text:
1. A method of making a composition, wherein said method consists essentially of the following steps: providing a shaped support; incorporating a solution, consisting essentially of a metal component at a concentration of said solution so as to provide the desired metal content in the final composition and a chelating agent, into said shaped support to provide a metal-incorporated support; drying said metal-incorporated support at a drying temperature not to exceed 300° C. so as to provide a dried metal-incorporated support having a volatiles content in the range of from 1 to 20 wt % LOI thereby creating an available pore volume; incorporating a polar additive without a metal component into the available pore volume of said dried metal-incorporated support in an amount sufficient to fill at least 75% of the available pore volume with said polar additive to thereby provide an additive impregnated composition; treating said additive impregnated composition by exposing said additive impregnated composition to a gaseous atmosphere containing hydrogen at a hydrogen partial pressure in the range of from 1 bar to 70 bar at a temperature ranging upwardly to 250° C. and for a hydrogen treatment time period in the range of from 0.1 hour to 100 hours to provide a hydrogen treated additive impregnated composition; and sulfiding said hydrogen treated additive impregnated composition to provide an activated additive impregnated composition.
