Recent advances in promoting dry reforming of methane using nickel-based catalysts

Dry reforming of methane (DRM) is an efficient way for CO 2 utilization to convert CH 4 and CO 2 to syngas (H 2 and CO), which is an ingredient to produce hydrogen and methanol and hydrocarbons via Fischer-Tropsch process. Considerable attention is drawn to Ni-based catalyst due to its remarkable re...

Description
Summary:Dry reforming of methane (DRM) is an efficient way for CO 2 utilization to convert CH 4 and CO 2 to syngas (H 2 and CO), which is an ingredient to produce hydrogen and methanol and hydrocarbons via Fischer-Tropsch process. Considerable attention is drawn to Ni-based catalyst due to its remarkable reactivity for CH 4 and CO 2 conversion. However, the weakness of sintering and coking restrains its industrial applications. The successful design of cost-effective, efficient and stable Ni-based catalysts would be a grand breakthrough for the technology. Herein, the thermodynamic analysis and the mechanisms of sintering and coking are presented. Then, the strategies for improving the performance of catalysts are elaborated as follows, with 1) supports improving the particle dispersion of nickels and changing the reaction process for the hindrance of coking; 2) promoters for regulating the nickel's chemical properties to enable catalytic DRM performance; 3) catalysts obtained by varied preparation methods possess different sizes and interactions. Finally, the challenges and future perspectives are highlighted. The achievements of dry reforming of methane over Ni-based catalysts are presented with focus on the modification factors to enhance sintering and coking resistance, elaborated in the context of support, promoter, and preparation.
