Abstract
Improved desulfurization compositions are provided for removing substantial fractions of sulfur, sulfur complexes, and sulfur compounds from liquid hydrocarbons such as crude oil and fuels. The preferred compositions comprise respective quantities of an alkylphenol ethoxylate, an amine, and an alkali metal nitrite. The compositions may be contacted with liquid hydrocarbons to achieve high levels of desulfurization.
