Modeling Partial Oxidation of Methane in the Microreactor, Porous Medium for Hydrogen Production

Considering the strict laws that have been established to reduce combustion pollution and control, it is necessary to consider a new approach to energy supply in the future. Accordingly, hydrogen can be introduced as an alternative fuel to fossil fuels because this energy source is very compatible with the environment and when it reacts with oxygen as a fuel, it produces only water. Also, hydrogen is an important chemical reserve in many chemical industries. The partial oxidation process of hydrocarbons is one of the important applications of the internal combustion. It is a porous medium for synthesis gas production and hydrogen production. Considering the various industrial methods for producing hydrogen in high capacities, attention has been directed to the processes that are in small capacity and are suitable from the economic point of view. Partial oxidation processes in porous media are among these processes. In this study, along with the theoretical investigation of the partial oxidation of methane in the porous medium, modeling was done for a tubular reactor filled with porous medium materials. In the next step, investigating the effects of porous medium conditions, including the structural characteristics of materials such as particle diameter, porosity, and physical changes of the reactor, including the diameter and length of the reactor, and finally, the equivalence ratio of fuel and air, and changes in the intensity of the fuel inlet flow with an approach to producing more Hydrogenation is done.
