| Summary: | 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. |
