Emulsification of Water and Pyrolysis Oil by Sorbitol Derivative Surfactants

Abstract:

Effects of sorbitol derivative surfactants on the stability of pyrolysis oil emulsion prepared from plastic waste were experimentally investigated. The water-pyrolysis oil mixture emulsified by Sorbitan monooleate (Span 80) surfactant is more stable than the water-in-oil emulsions prepared by other Sorbitol derivative surfactants which have lower hydrophilic-lipophilic balance (HLB) numbers. The Span 80 concentration of 1.5% by volume was found to produce the most stable emulsion and the smallest average water droplet. This optimal surfactant concentration is the same as critical micelle concentration.
