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 tripiperidinophosphine oxide to inhibit coke formation on the heat transfer surfaces. The tripiperidinophosphine oxide is essentially free from contributing to corrosion and from producing catalyst-impairing by-products.
