Steam pyrolysis of methylcyclohexane has been investigated in a tubula
r reactor at atmospheric pressure in the temperature range 953-1073 K.
Using non-linear regression, the overall decomposition was found to b
e approximately first-order with a pre-exponential factor and activati
on energy of 1.71 x 10(11) s(-1) and 209.0 kJ mol(-1), respectively. T
he experimental product yields and conversion could be satisfactorily
simulated using a molecular model consisting of an overall primary rea
ction and twenty-four secondary reactions. (C) 1997 Elsevier Science S
