Adsorption Desulfurization of Actual Heavy Crude Oil Using Activated Carbon

Bioremediation of Heavy Crude Oil Contamination

Crude oil contamination is one of the major environmental concerns and it has drawn interest from researchers and industries. Heavy oils contain 24-64% saturates and aromatics, 14-39% resins and 11-45% asphaltene. Resins and asphaltenes mainly consist of naphthenic aromatic hydrocarbons with alicyclic chains which are the hardest to degrade. Crude oil biodegradation process, with its minimal en...

Fixed Bed Adsorption Studies of Rhodamine B Dye Using Oil Palm Empty Fruits Bunch Activated Carbon

Global environmental pollution challenges can be alleviated if proper disposal and conversion of wastes is promoted. An attempt of converting waste to wealth was made in this study by converting oil palm empty fruits bunch to activated carbon through chemical activation with potassium hydroxide which was used for adsorption of Rhodamine B dye from waste water. Fixed-bed column adsorption system...

recycling of residual oil fly ash: synthesis and characterization of activated carbon by physical activation methods for heavy metals adsorption

in this study, the recycling possibility of residual oil fly ash (rofa) towards preparing activated carbon and its application in environmental remediation through adsorbing cu (ii) and pb (ii) ions from aqueous solutions were investigated. activated carbons were prepared using two different physical activation methods such as under steam flow at 950 0c, and combined steam and co2 flow at 850 0...

Novel Methods for Desulfurization of Fuel Oils

Because of the requirement for low sulfur content of fuel oils, it is necessary to develop alternative methods for desulfurization of heavy fuel oil. Due to the disadvantages of HDS technologies such as costs, safety and green environment, new methods have been developed. Among these methods is ultrasoundassisted oxidative desulfurization. Using ultrasound-assisted oxidative desulfurization, co...
