Abstract
A method of determining the identity of a petroleum coke sample including obtaining a nuclear magnetic resonance (NMR) measurement of the sample, determining a relaxation decay value of a fluid in the sample from the NMR measurement, comparing the relaxation decay value to relaxation decay values of known petroleum coke materials in a reference group to determine whether the petroleum coke is one of the known materials.
