Review on the catalytic tri-reforming of methane - Part I: Impact of operating conditions, catalyst deactivation and regeneration

Tri-reforming of methane (TRM) allows the production syngas with a low environmental impact, an optimal energetic consumption, and modular H2/CO molar ratio. However, despite large number publications devoted to TRM reaction, this process is still in its infancy faces technical issues due catalyst deactivation by formation solid carbon, thermal sintering, vapor-solid reactions, poisoning. Moreover, reaction also highly dependent on operational conditions. This article provides critical analysis last achievements reaction. First, thermodynamic, kinetic mechanism aspects are presented commented. Then, impact conditions analyzed. Finally, main reasons associated methods for regeneration discussed. In parallel, catalytic efficiency tentatively linked physico-chemical properties catalyst, recommendations proposed future work process.
