of their Use in IndustryThe most important goal of this research is the numerical study of methane self-heating reforming process with the help of three-dimensional modeling. With the help of modeling results, changes in temperature and concentration of components can be studied at any point inside the reactor. The importance of this modeling refers to the provision of information for the design of reforming systems, which can be used to prevent problems such as the formation of hot spots inside the reactor that lead to damage to the catalyst. Therefore, CFD modeling helps to optimize the design of the reactor and determine the conditions that lead to the improvement of fuel conversion efficiency. Also, the time and cost required for the implementation of new ideas and designs will be reduced. A lot of research has been done for self-heating reforming of methane on conventional catalysts such as nickel, platinum, palladium, etc. In many of these studies, the catalyst used for partial oxidation and reforming is different from steam.
