✦ Synopsis

An experimental study of axıal temperature profiles in a nonadiabatic tubular fixed bed reactor has been made under the transient operation The catalytıc carbon monoxıde oxıdation occuring on a Pt/alumına catalyst has been used Unlike the adiabatic conditions the velocity of a traveling temperature wave in a nonadiabatical arrangement depends on its axial position In certain regions of inlet concentration multiple temperature fronts have been observed For low inlet (\mathrm{CO}) concentration a downstream temperature wave results and the lower (kınetıc) steady state is dominant For high inlet CO concentration an upstream propagating front results and the upper steady state is dominant For a downstream moving wave oscillations of wave velocity, hot spot temperature and exit conversion have been measured For certain operating conditions periodic behavior of temperature profiles in the reactor has been observed
