ABSTRACT:
Inhibiting coke formation on heat transfer surfaces used to heat or cool a petroleum feedstock at coke-forming conditions. The heat transfer surfaces are treated with an effective amount of S,S,S-trihydrocarbyl phosphorotrithioate to inhibit coke formation on the heat transfer surfaces. The phosphorotrithioate is essentially free from contributing to corrosion and from producing catalyst-impairing by-products.
