in this work the effect of various surfactants such as linear alkyl benzen sulphonate LABS as anionic surfactant tetradecyl trimthylammonium bromide TTAB as cationic type and ethoxylated dodecyl alcohol 2,3,4,5.5 and 7 mole ethoxylated as non-ionic surfactant as well as nano-tetraphenyl porphyrin TPP on stabilization of asphaltene emulsion were studied nano-TPP was synthesized once by water addition using ultrasound and other by ethanol addition using microwaves. it was shown that p-p interaction between asphaltene molecules and nanoporphyrin, as well as hydrogen bond formations with surfactants molecules have the main effects on asphaltene emulsion stability.
