Steam-Reforming

The steam-reforming consists in the catalyzed reaction of the proposed fuel with water, situation remarked by large energy consumption. It is important to define all parameters at this time. Selectivity is the capacity of the catalyst to promote formation of a specific product at a well-defined thermodynamic condition. It can be defined as the molar fraction of one product at one specific condition. Another important parameter is the catalyst activity. It could be defined as the catalyst capability of converting the fuel.

The catalyst is generally the central focus of most studies in order to promote the reaction at lower temperatures (usually between 350-700°C), and to minimize systems’ dimensions and costs related to construction materials [1]. Frequently, the desired product is hydrogen [2-13], but catalysts could be developed for higher selectivity to yield other compounds.
