In order to study the thermal cracking of atmospheric gas oil a pilot plant was designed and setup. Several
experiments were carried out. The operating conditions were COT (coil outlet temperature), steam ratio and feed flow
rate. The ranges of these variables were respectively equal to 716-884°C, 0.46-1.136 and 0.977-6.02 g/min. The
obtained minimum and maximum yield of ethylene was respectively equal to 1.7% and 30.9% as well as the maximum
yield of propylene was 12.2%.In order to predict the coke formation rate in different operating conditions, a molecular
model developed for thermal cracking of atmospheric gasoil. The developed model can predict the yield distribution of
main products and coke formation rate. To analyze and characterize the atmospheric gasoil, a novel algorithm was
applied. This algorithm utilized density, ASTM distillation curve, H/C ratio and the total aromatic fraction and
generates the detail analysis of feedstock including paraffinic, naphthenic, aromatics and poly aromatic compounds.
