Fouling resistances of solutions of olefins in kerosene were measured on a hot wire probe and an annular probe operating in parallel at liquid temperatures of about 80°C and heat fluxes from 180‐350 kW/m 2 . Straight chain terminal olefins, octene‐1 and decene‐1 showed little fouling, whereas hexadecene‐1, and the cyclic olefins 4‐vinyl‐cyclohexene, indene and dicyclopentadiene all showed marked fouling. The effects of heat flux, air versus nitrogen saturation, and the presence of an inhibitor were determined. The probable mechanism of fouling is discussed.
