Abstract
A process for substantially decreasing fouling in a refinery unit. The process comprises preheating a feed to said refinery unit reactor zone and there-after introducing the feed into said refinery unit reactor zone for reaction. The feed is preheated for a time and at a temperature sufficient to cause an effective amount of any polymers and/or oligomers contained in feed to decompose or unzip to substantially reduce fouling in the refinery unit.
