Significance and Use:
5.1 The ash content is one of the properties used to evaluate petroleum coke and indicates the amount of undesirable residue present. Acceptable ash content varies with the intended use. Ash values are for use in comparing the relative purity of petroleum coke. Generally, higher ash content reflects lower quality of petroleum coke.
