7. A composition as recited in claim 6 , wherein the weight ratio of n-formylmorpholine to said mixture of 3-(octyloxy) propylamine and 3-(decyloxy) propylamine is in the range of from 0.1:1 to 8:1.
8. A composition as recited in claim 6 , wherein said active metal precursor is a metal compound that includes a Group 9 and Group 10 metal component selected from the group consisting of cobalt and nickel, and wherein said Group 9 and Group 10 metal component is present in said composition in an amount in the range of from 5 wt. % to 50 wt. %.
9. A composition as recited in claim 8 , wherein said support material that is loaded with said active metal precursor and said additive, is treated with hydrogen.
10. A composition as recited in claim 9 , wherein said support material that is loaded with said active metal precursor and said additive and treated with hydrogen, is treated with a sulfur compound.
11. A composition as recited in claim 1 , wherein said ether amine compound is selected from the group consisting of hexyloxypropylamine, isohexyloxypropylamine, 2-ethylhexyloxypropylamine, octyloxypropylamine, decyloxypropylamine, isodecyloxypropylamine, dodecyloxypropylamine, isododecyloxypropylamine, isotridecyloxypropylamine, and mixtures of any two thereof.
