Abstract Production of syngas as a raw and intermediate material is very important for industries. Despite numerous attempts made in industry, there are still many challenges in its production. One of these challenges is effect of temperature on catalyst deactivation and conversion which has a direct effect on yield of process. Thus, this study tends to simulate methane steam reforming process in monolith micro-reactors and evaluate effect of temperature on reactor performance. The values obtained were evaluated by results of experiments and simulations conducted and the model was confirmed. Then, effect of temperature was examined on yield. This study first modelled tubular reactor synthetically. Then, values were validated by results of other studies. Finally, energy, mass and momentum equations as well as the reaction was incorporated in the model. Geometry used in this process was one of the models for monolith reactors used in Knox process in industry. This geometry included a multi-channel porous wall monolith reactor in which reactions occurred within the wall. As the results showed, porous wall monolith reactor allowed 70% conversion. Coke formation which deactivates catalyst can be avoided by keeping temperature over 800 ºC. Thus, this study tended to keep constant temperature (800 ºC) by applying external heat through temperature thermal jacket.
