CARBON HOLDI.(3)
Producing graphene or carbon fiber involves extracting coal sample from location, performing spectral analysis on coal sample to detect hydrogen to carbon ratio of coal sample, concentration of contaminant in coal sample.
TARGETT M, LINDEMANN G W, ATKINS C A
Processing coal, comprises e.g. subjecting raw coal to liquefaction process effective to form pitch resin, and subjecting the pitch resin to variable crystallinity spinning process effective to form raw fiber.
TARGETT M, YURCHICK C L
Producing reduced graphene oxide from coal by thermally processing coal, oxidizing thermally processed coal to form coal oxide, and forming reduced graphene oxide comprising impurity atoms from coal oxide.
