3. Relation between asphaltene adsorption on the nanoparticles surface and asphaltene precipitation inhibition during real crude oil natural depletion tests

Yaser Ahmadi

Articles in Press, Accepted Manuscript, Available Online from 05 September 2021

http://dx.doi.org/10.22050/ijogst.2021.291675.1600

Abstract
  Using nanoparticles for adsorbing asphaltene was known as one of efficient methods among researchers for upgrading of real oil samples in comparison to other expensive mechanical treatments or even solvents (such as n-pentane and n-heptane) and surfactants. In this study, Nickel zeolite oxide nanoparticles ...  Read More
