1. A method of producing carbon fiber, 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 including an impurity therein and having an initial hydrogen to carbon ratio greater than 0.7;
beneficiating the amount of raw coal to selectively remove at least some of the impurity comprising heteroatoms to form beneficiated coal;
processing the beneficiated coal to produce a pitch; and
modifying at least some of the pitch to produce the carbon fiber;
wherein the carbon fiber includes a selected amount of a remainder of the impurity.
