Alcoxilato sulfate liquid shell of cashew nuts as a composition of surfactant for applications of renewable oil recovery enhanced

摘要

The present invention provides methods of producing a sulfate surfactant alcoxilato liquid shell of cashew walnuts for a natural alcoxilatau00e7u00e3o alkylphenol using polypropylene oxide(PO), and / or ethylene oxide (EO), followed by a reaction of sulphation.The surfactant sulfate alcoxilato liquid shell of chestnut of cashew nuts of the present invention is produced by a method easy and cost effective.The hydrophobic surfactant natural present invention finds use in applications EOR where he is used for solubilization and mobilization of asphaltene containing optionally oil, wax, naphthalene,And for environmental cleanup.In addition, the version of the alcoxilato of cardanol sulfated surfactant hydrophobic natural of this invention can be used as a surfactant ionic not ultra high molecular weight.Another advantage is that the composition is a surfactant of renewable basis which is non-toxic and biodegradable.
