| Abstract | The deposition of coke-like products was studied in the postcracking zone ( < 500°C) of a laboratory pyrolysis reactor coupled with a thermobalance. By means of 14C-labelled hydrocarbons, data on the contribution of individual feedstock components to the coke formation were obtained. Reactive, volatile hydrocarbons, like toluene and hexyne, do not contribute significantly to the deposits if they pass the postcracking zone undecomposed. The results favour as a dominant mechanism in transfer line heat exchanger fouling the condensation of heavy components of the fuel oil fraction and precipitation of tar droplets. At a catalytically active steel surface the coke formation from a cracker effluent at 500°C is strongly influenced by steam dilution. |
