Organo-sulfur compounds as high temperature antifoulants |
摘要 |
This invention relates to a process of inhibiting or preventing fouling (i.e., preventing the adhesion of deposits from hydrocarbon on surfaces) at elevated temperatures which comprises adding to hydrocarbon an antifouling (preventing) amount of an organo-sulfur compounds having a high sulfur content. In the preferred embodiment, the organo-sulfur compound has at least 5% sulfur. An embodiment is a heterocyclic compound, a dithiole-thione. These organo sulfur compounds are particularly effective at elevated temperatures of at least about 500 DEG F.
