Iron-polyphenol complex nanoparticles for removal of greenhouse gas emission from bitumen and formation of paraffins

The removal of greenhouse gas (GHG) emission from bitumen used in the construction of flexible pavement by iron-polyphenol complex nanoparticles (Fe-PNP s ) has been examined in the study. Laboratory studies indicated the removal of carbon dioxide (CO 2 ) with Fe-PNP s is a function of the amount of additive (Fe-PNP s ). From the experimental data, it was found that the reduction of CO 2 increases with increasing amount of additive up to a dosage of 4% (by weight of bitumen) without severely changing the basic engineering properties of the bitumen. The reduction of GHG is due to the conversion of the CO 2 to a mixture of hydrocarbon in the presence of Fe-PNP s . The characterization of the additive by SEM, FTIR, UV, and XRD indicated the formation of the Fe-PNP s . The analysis of the basic engineering properties of bitumen such as penetration value, softening point of the bitumen, flash point, fire point, and ductility in the presence of additive as well as without the additive were studied and reflected a noticeable effect in the reduction of the CO 2 . The reduction of GHG by Fe-PNP s minimizes the environmental impact and saving energy by increasing the yield of hydrocarbons.
