A new catalyst system for conversion of liquid hydrocarbon into hydrogen rich gas was studied. Catalyst stability test was performed successfully for > 1400 hr using heavy naphtha fuel. The concept of thermo neutral reforming (TNR) is described. The TNR catalyst configuration showed hydrogen spillover effect with heavy naphtha fuel. TPR results confirmed integration of active metals according to the designed TNR catalyst configuration. This is an abstract of a paper presented at the 18th Saudi Arabia-Japan Joint Symposium (Dhahran, Saudi Arabia 11/16-17/2008).
