Abstract

A precursor having at least five percent of lignin based coke and d002 spacing of more than 3.36 angstroms and less 3.44 for making graphite. Methods for making a green/graphite article include mixing coke derived from a petroleum product, a coal product or a bitumen product with coke derived from lignin. Alternatively, the precursor material for the various types of coke may be mixed and coked together. The mixture may be formed into a desired shape. The article may be subsequently carbonized and graphitized. The amount of lignin derived coke comprises a sufficient quantity to change at least a selected property of the graphite article.
