Phosphorothioate coking inhibitors

Inhibiting coke formation on heat transfer surfaces used to heat or cool a petroleum feedstock at coke-forming conditions by using phosphorothioates. Preferably the heat transfer surfaces are treated with an effective amount of S,S,S-trihydrocarbyl phosphorotrithioate, either by pretreatment or by a...

Summary:Inhibiting coke formation on heat transfer surfaces used to heat or cool a petroleum feedstock at coke-forming conditions by using phosphorothioates. Preferably the heat transfer surfaces are treated with an effective amount of S,S,S-trihydrocarbyl phosphorotrithioate, either by pretreatment or by admixture of the phosphorotrithioate with the feedstock.
