A pitch composition suitable for spinning may comprise: a pitch having a softening point temperature (T) of 400° C. or less, and an oxidation onset temperature (OOT) at least 10° C. below the Tat a ramp rate of 10° C./min. A carbon fiber may comprise: a carbon fiber produced from a pitch composition, wherein the pitch composition comprises: a pitch having a softening point temperature (T) of 400° C. or less, and an oxidation onset temperature (OOT) at least 10° C. below the Tat a ramp rate of 10° C./min.

Sulfur-crosslinked olefins, particularly sulfur-crosslinked heavy hydrocarbon products having one or more sulfur-crosslinked olefin moieties, may undergo pyrolysis to form sulfur-doped porous carbon having high BET surface area values. Pyrolysis to form the sulfur-doped porous carbon may be particularly efficacious in the presence of a hydroxide base. BET surface areas up to 2000 m/g or even higher may be obtained. Such sulfur-doped porous carbon may be prepared by combining a heavy hydrocarbon product with sulfur, heating to a first temperature state to form a liquefied reaction mixture containing a sulfur-crosslinked heavy hydrocarbon, homogeneously mixing a hydroxide base with the liquefied reaction mixture, and pyrolyzing the sulfur-crosslinked heavy hydrocarbon to form sulfur-doped porous carbon.
