A review of dry (CO 2) reforming of methane over noble metal catalysts. Recent advance in dry reforming of methane over Ni-Based catalysts. The authors declare no conflict of interest. Kinetic analysis, performed in order to find the suitable mechanistic model that adequately describes the reaction rate and defines the chemical process, can be used for the optimization of the catalyst design. To study the mechanisms of DR reaction and to determine the related kinetic parameters is fundamental for developing effective catalytic systems and consequently for commercializing methane-reforming technologies. Although noble metals are very active and more coke-resistant than Ni-based catalysts, the former systems are preferred to noble metal-based samples, as they are cheaper and widely available, making DR reaction a more industrially-viable process. The major problem encountered in the process is the rapid catalyst deactivation by carbon deposition. ![]() Common catalysts for DR reaction are composed either by noble metals (Pt, Rh, Ru, Ir) or transition metals, such as Ni, Co and Fe. The biogas quality is often adequate to DR reaction but its use can be enhanced through the mentioned process. Besides, CH 4 and CO 2 gases are the main constituents of biogas, a fuel that is produced extensively by various anaerobic biological waste treatments. The reduction of CO 2 and CH 4 emissions into the atmosphere and their possible recycling, induced a growing interest in dry reforming (DR) reaction (CO 2 + CH 4 → 2H 2 + 2CO ΔH° 298 K = 247 kJ/mol), able to produce syngas, a building block for the synthesis of different chemicals and oxygenated fuels. In the last decade the growing energy demand, furnished primarily from fossil fuels, have created environmental issues due to the generation of greenhouse gases (CO 2 and CH 4).
