Abstract
A method is disclosed for decoking a vertical tube reactor. The decoking process involves contacting the coke with an oxidizing substance in the presence of a carrier liquid to oxidize the coke and produce carbon dioxide, water and by-products. The post-oxidation temperature is maintained below the critical temperature of the carrier liquid at the local pressure. The conditions of the coke oxidation are maintained in such a manner as to assure that the by-products are substantially suspended or dissolved in the liquid.
