Zusammenfassung:	The present invention is a method for mitigating the fouling from thermally cracked oils by minimizing the residence time at the temperature when the fouling is highest. A method for mitigating the fouling of process equipment by thermally cracked petroleum oils with diene values by UOP method number 326-82 of 4 grams iodine/100 grams oil or greater comprising raising the temperature of the petroleum oil in the process to above 580 DEG F.
