ABSTRACT
Due to the limitations of existing methods, steam reforming is the most important method of hydrogen production. In this study, we intend to investigate the potential of two Rh/Al2O3 and Cr/Al2O3 catalysts in the conversion of naphthalene in the steam reforming process. For this purpose, the experimental method was first described in a fluidized bed reactor. In the next step, the effect of various parameters such as catalysts, temperature and steam/carbon ratio on naphthalene conversion was investigated. With increase in temperature from 700°C to 850°C, the naphthalene conversion increased from 43.2% to 82.8% for Rh/Al2O3 and from 39.0% to 77.9% for Cr/Al2O3. Hydrogen production increased as the injection of steam into the reactor increased which can be explained based on the principle of Le Chatelier.
