✦ Synopsis

Reasons for studymg a purely thermodynanuc

approach to the problem of carbon formation m the steam reformmg of od feedstocks are outhned The Newton-Raphson method was successfully applied to the problem of solvmg the complex eqmhbna equations Usmg the concept of the feasible repon of gas composlhon, the problems of divergence often encountered wtth tha techmque were avoided Furthermore, the boundanes of temperature and pressure at whxh carbon will begm to form can be predlcted for any specdied feedstock and steam Input These boundanes were found to be sensltlve to the steam to carbon atom rat10 for a gven fuel and the analysts demonstrated the temperature and pressure effect on the sensltlvity of carbon formation
