Petroleum coke is a non-polar material which means it is not dispersible. Coke is insoluble and thus limits the development of petroleum coke based product. The dispersibility study of nitrated coke is an important prerequisite in order to understand the pattern of dispersibility over the time. To understand the nature and constitution of nitrated coke, or to separate the organic matter of coke for its conversion to useful products, detailed systematic studies on the solubilization characteristic of cokes in organic solvents is a must. This study will compare the stability of the suspension (colloid) among three samples of nitrated cokes (difference in nitration temperature) versus time. The reasons behind the solubility and the dispersibility characteristic of nitrated coke are also discussed. The experiment conducted will involve the usage of UV-vis spectrophotometer. The earlier findings are showing that the nitrated cokes dispersed in acids and neutral solution. Apart of that, treated cokes dissolved in high pH solution. A recommendation is suggested whether a 'new water dispersible solid coke' should be further developed or vice versa. The complete substitution is, if ever achievable, a long term goal. Possible problem encountered also will be also being discussed throughout this report.
