Reforming of methane: Effects of active metals, supports, and promoters

ABSTRACTABSTRACTThe dry reforming reaction (DRM) had capacity to mitigate the greenhouse gases from environment as well as to produce syngas as a chemical feedstock. Various doped metal oxides, supported metal catalysts and promoted catalyst system over different supported metal catalysts had profound activity toward this specific reaction. Herein, a sequential review on DRM is presented which covers most of the excellent and conceptual work of this field from the last two decades. The review covers 8 active metals i.e. Fe, Co, Ni, Ru, Rh, Pd, Ir, Pt dispersed over 12 support system as activated carbon or Char, MgO, CeO2, La2O3, Y2O3, TiO2, Si2O3, Al2O3, ZrO2, SiC BN, Clay for DRM reaction. Further under each support, a deep literature review of a long range of promotors (total 35) belonging to different groups of periodic tables is elaborated. At the end, a brief about the state-of-the-art of possible industrial potent catalyst and the future research portfolio for catalytic advancement are presented.GRAPHICAL ABSTRACTKEYWORDS: DRM review12 support35 promotors8 active metalsperiodic groups AcknowledgmentsThe authors would like to extend their sincere appreciation to Researchers Supporting Project number (RSP2023R368), King Saud University, Riyadh, Saudi Arabia.
