1. A method of processing a feedstock comprising the steps of:
providing a hydrocarbon feedstock which contains oxygen, wherein said hydrocarbon feedstock comprises a first solubility;
contacting said hydrocarbon feedstock with one or more primary or secondary mono-amine or amide, under non-pyrolytic conditions;
liquifying said hydrocarbon feedstock with said one or more primary or secondary mono-amine or amide;
wherein said step of liquifying said hydrocarbon feedstock with said one or more primary or secondary mono-amine or amide comprises breaking chemical bonds in said hydrocarbon feedstock;
and
generating a reacted liquid phase as a result of said step of liquifying said hydrocarbon feedstock with said one or more primary or secondary mono-amine or amide,
wherein said reacted liquid phase comprises 0.25 to 25 wt % nitrogen,
wherein said reacted liquid phase has at most 85% of said oxygen than originally found in said hydrocarbon feedstock,
wherein of said reacted liquid phase comprises a second solubility which is greater than said first solubility of said coal derived hydrocarbon feedstock;
wherein said reacted liquid phase is dissolvable in a solvent having a Hansen solubility parameter less than 27 MPa0.5; and
wherein said reacted liquid phase has a softening point of less than 400° C.
