Methods for forming resins and other byproducts from raw coal
A method of producing at least one or more resins is disclosed. The method includes providing an amount of raw coal. The raw coal includes one or more impurities therein. The method also includes beneficiating the amount of raw coal to selectively removing at least a portion of some of the one or more impurities in the raw coal to form beneficiated coal. Additionally, the method includes processing the beneficiated coal to produce an amount of pitch. The method further includes modifying at least some of the pitch to produce the one or more resins. The one or more resins include a selected amount of a remainder of the one or more impurities that were not removed while beneficiating the amount of the raw coal, processing the beneficiated coal, and modifying at least some of the pitch.
1. A method of producing a resin, comprising:
providing an amount of raw coal, the raw coal selected based on at least one of a destructive or non-destructive chemical analyzation technique, the raw coal comprising a hydrogen to carbon ratio that is greater than about 0.7 and including an impurity;
beneficiating the amount of raw coal to selectively remove at least some of the impurity to form beneficiated coal;
processing the beneficiated coal to produce a pitch; and
modifying at least some of the pitch to produce the resin;
wherein the resin includes a selected amount of a remainder of the impurity.
2. The method of claim 1 , wherein beneficiating the amount of raw coal includes removing at least 75 wt. % of at least one of mercury, arsenic, cadmium, water, or volatile compounds.
3. The method of claim 1 , wherein processing the beneficiated coal include pyrolyzing the beneficiated coal.
4. The method of claim 3 , wherein pyrolyzing the beneficiated coal includes heating the beneficiated coal to about 400° C. to about 650° C. at atmospheric pressure.
5. The method of claim 1 , wherein processing the beneficiated coal includes at least one of subjecting the beneficiated coal to a direct liquefaction process, subjecting the beneficiated coal to an indirect liquefaction, or using membranes.
6. The method of claim 1 , wherein modifying at least some of the pitch includes modifying the at least some of the pitch to form one or more resin precursors.
7. The method of claim 3 , wherein the one or more resin precursors includes at least one of C2 compounds, C3 compounds, or C4 compounds.
8. The method of claim 3 , wherein the one or more resins precursors includes benzene compounds, toluene compounds, halogen compounds, or phenols.
9. The method of claim 3 , wherein the one or more resin precursors includes methanol.
10. The method of claim 1 , wherein the resin includes at least one of polyethylene or polypropylene.
11. The method of claim 1 , wherein the resin includes polyacrylonitrile.
12. The method of claim 1 , wherein the resin includes at least one of polyurethane resins, cyanate ester resins, epoxy resins, methacrylate resins, polyester resins, or polycyclic aromatic hydrocarbons.
13. The method of claim 1 , further comprising:
capturing syngas; and
modifying the syngas to form some of the resin.
14. The method of claim 1 , wherein modifying at least some of the pitch to produce the resin includes modifying some of the pitch to produce the resin and using a remainder of the pitch to form an additional advanced carbon material.
15. The method of claim 14 , wherein the additional advanced carbon material includes carbon fibers.
16. A method of producing an advanced carbon material at a single processing facility, comprising:
providing an amount of raw coal to the single processing facility, the raw coal selected based on at least one of a destructive or non-destructive chemical analyzation technique, the raw coal comprising a hydrogen to carbon ratio that is greater than about 0.7 and including an impurity;
beneficiating the amount of raw coal at the single processing facility to selectively remove at least some of the impurity to form beneficiated coal;
processing the beneficiated coal at the single processing facility to produce a pitch; and
modifying at least some of the pitch at the single processing facility to produce a resin;
wherein the resin includes a remainder of the impurity.
17. The method of claim 16 , wherein beneficiating the amount of raw coal includes removing substantially all of at least one of mercury, arsenic, cadmium, water, or volatile compounds.
18. The method of claim 16 , wherein processing the beneficiated coal includes at least one of pyrolyzing the beneficiated coal in a mild temperature pyrolysis process, subjecting the beneficiated coal to a direct liquefaction process, subjecting the beneficiated coal to an indirect liquefaction process, or using membranes.
19. The method of claim 16 , wherein modifying at least some of the pitch includes modifying the at least some of the pitch to form a resin precursor, the resin precursor including at least one of C2 compounds, C3 compounds, C4 compounds, benzene compounds, toluene compounds, halogen compounds, or phenols.
