Abstract

Fouling rate data have been obtained by passing kerosine at a low flow rate through a small horizontal tubular furnace. Substantial circumferential variations in surface temperature and fouling rate occurred during varporization, the highest rates being at the bottom of the tube where surface temperatures were the lowest. Fouling rates generally increased as pressure increased from 1 to 2.5 bar, but were reduced markedly either by decreasing the feedstock oxygen content or by raising the wall superheat. All the observations are consistent with fouling occurring predominantly via autoxidation and cracking-synthesis mechanisms for the liquid and vapor phases, respectively.
