Sulfonation method for efficient scale-up synthesis of janus carbon nanomaterials from biomass waste
Aramco Services Company, Houston, TX (US);

Abstract
A method of preparing an enhanced oil recovery composition includes carbonizing a biomass waste material to provide carbon microparticles, functionalizing the carbon microparticles with a SO-containing gas such that the carbon microparticles include a hydrophilic surface, and grinding the carbon microparticles to provide carbon nanoparticles. The carbon nanoparticles include a hydrophilic surface and a hydrophobic surface. A method of enhanced oil recovery includes introducing an enhanced oil recovery composition including a carbon nanoparticle functionalized with a SO-containing gas and including a hydrophilic and hydrophobic surface into a hydrocarbon-bearing formation. The method includes displacing hydrocarbons from the hydrocarbon-bearing formation and recovering the hydrocarbons.
