Abstract
Methods for of processing an oxygen containing feedstock to an amine reacted liquid or solid phase with a different solubility, polarity and/or functionality may, in various embodiments, comprise steps of contacting the amine with an oxygen containing hydrocarbon with temperature to facilitate reactions to reduce the oxygen content and modulate the solubility, polarity and/or functionality of the products.
Claims17
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.
