Microemulsion based synthesis of Ni/MgO catalyst for dry reforming of methane

Abstract

The dry reforming of methane has been investigated with two sets of catalysts (pure Ni and Ni/MgO) prepared by microemulsion system.

Review on the catalytic tri-reforming of methane - Part II: Catalyst development

“…Several works related to the synthesis of catalysts prepared by microemulsion for DRM reaction have been reported [49,50]. However, the work of Kim et al is thus far the only one featuring the synthesis of TRM catalysts by microemulsion methods.…”

Thermal dry reforming of methane over La2O3 co-supported Ni/MgAl2O4 catalyst for hydrogen-rich syngas production

“…For co-support, MgAl 2 O 4 and La 2 O 3 were taken as 4:1 (wt. ratio) as co-support and prepared by microemulsion technique [31]. The 10% wt.…”

Engineering a Nickel–Oxygen Vacancy Interface for Enhanced Dry Reforming of Methane: A Promoted Effect of CeO2 Introduction into Ni/MgO

“…In addition to active metals, supports also play a crucial role in the DRM reaction. Basic supports, such as MgO, CaO, and La 2 O 3 , would be beneficial for DRM reaction as their basic characteristics will enhance acidic CO 2 adsorption. − In particular, MgO has been suggested as a suitable support material due to its low cost, high stability, and strong basicity. , Furthermore, the formation of a solid solution structure between MgO and NiO is likely, which on the one hand could potentially enhance the interaction between Ni and MgO; on the other hand, it may hinder the reduction of NiO and thus having an adverse effect on the DRM reactiion . Furthermore, supports also have a significant effect on the coking or metal sintering, which also needs to be considered in the implementation on the industry scale. , …”
