this paper, a 2-dimensional model has been established for ethane cracking in a thermal cracker in laminar flow, using amolecular mechanistic model for ethane cracking. The model, consisting of 9-coupled partial diferential equations,is solved using the backward implicit numerical scheme. The resulting product distribution and temperature profilesare predicted throughout the reactor. The concentrations of acetylene and propylene show a maximum within the reac-tor. The efect of certain operational parameters - tube radius, wall temperature and mass flow rate - is also studiedon these profiles. The parameters are varied in the range of 0.005-0.0125 m for tube radius, 1.25 kg/hr-2.5 kg/hr foroC for tube wall temperature. It is observed that an increase in wall temperature and anincrease in tube radius or decrease in flow rate favours the conversion of ethane.
