“…Hydrogen can be produced from biogas via methane dry reforming or biogas reforming with added steam, providing an opportunity to convert carbon dioxide into valuable fuels [1][2][3]. For example, synthetic gas can readily be generated directly from biogas for high temperature fuel cells (HTFCs) including molten carbonate fuel cells (MCFCs) and solid oxide fuel cells (SOFCs).…”

“…In addition, a highly active NiCu alloyed catalyst supported on Ce 0.9 Gd 0.1 O 2-1 (NiCu/CGO) has recently been developed for the integrated biogas SOFC process and showed increased resistance against coke deposition and metal sintering upon its utilization as a SOFC anodic material, thus stabilizing active metal sites for biogas dry reforming [11]. Another strategy for increasing catalyst stability is the addition of steam to biogas, which not only helps to suppress carbon formation but also controls the composition of the product gases easily by adjusting the inlet steam/CO 2 ratios [1].…”

Steam Reforming of Biogas over CeO2-Coated Ni–Al Plate Catalysts

Hydrogen production via steam reforming of a simulated biogas was achieved in a temperature range of 500-800°C over a plate-type Ni-Al catalyst. To enhance the catalytic activity of the Ni-Al catalyst, a pretreatment process involving pre-oxidation with sequential reduction was employed prior to the reforming reactions. The activated Ni-Al catalyst exhibited increased methane conversion depending on the pre-oxidation temperature. Studies using X-ray diffraction and scanning electron microscopy suggested that the catalyst surface was restructured upon pretreatment, ultimately improving the catalytic activity. To increase its catalytic stability, CeO 2 was employed additionally as a structural promoter to prevent both Ni sintering and carbon deposition. The durability of the CeO 2 -coated Ni-Al catalyst was improved significantly, particularly upon addition of C2.8 wt% of CeO 2 , with ca. 75 % of CH 4 conversions being achieved without deactivation over 100 h at 700°C. The influence of the preoxidation temperature, reforming temperature, and steam/ CH 4 ratio on reforming over a CeO 2 -Ni-Al catalyst was also elucidated. In addition, the potential roles of CeO 2 in the enhancement of activity and stability were discussed. Graphical Abstract

“…Biogas has been interested in many countries due to the concerns in energy security. It is similar to the natural gas which provides most hydrogen produced in the world [1,2]. Biogas technology has been developed in European countries early 2000s [3], but its usage and yield are currently increasing all over the world [4].…”
