“…The most commonly studied process for the reforming of biogas is dry reforming, in which the main components (CH 4 and CO 2 ) contribute to the production of syngas [28,29]. Steam reforming of biogas has also been investigated [30,31], but there are only few experimental data in the low temperature range [32].…”

This paper presents detailed study of biogas reforming. Model biogas with different levels of H 2 S is subjected to reforming reaction over supported Ni catalyst in a fixed bed reactor at 700 o C and 800 o C. In order to understand the poisoning effects of H 2 S the reactions have been initially carried out without H 2 S in the feed stream. Three different H 2 S concentrations (20, 50 and 100 ppm) have been considered in the study. The H 2 O to CH 4 ratio is maintained in such as way that CO 2 also participates in the reforming reaction. After performing the poisoning studies, regeneration of the catalyst has been studied using three different techniques i) removal of H 2 S from the feed stream ii) temperature enhancement and iii) steam treatment. Poisoning at low temperature is not recoverable just by removal of H 2 S from the feed stream. However, poisoning at high temperature is easily reversed just by removal of H 2 S from the feed stream. Unlike some previous reports [1,2], catalyst regeneration is achieved in shorter time frames for all the regeneration techniques attempted.

“…Most recently, different alternatives for biogas utilisation have been proposed such as biomethane production [2], combustion in a dual fuel diesel engine [3,4] or as feedstock in the dry reforming of CH 4 (DRM) [5,6]. In the latter case, high CO 2 concentration, up to 50%, makes biogas a perfect choice to be used as feedstock, resulting in a suitable syngas that can be used for hydrogen production [7,8], to feed a solid oxide fuel cell [9] or for hydrocarbons synthesis via the Fischer-Tropsch process [10]. Besides this, DRM using biogas can be classified as environmentally friendly due to the renewable character of the feedstock.…”

The utilization of biogas as carbon source for the co-production of filamentous-like materials and syngas is proposed. Catalysts with different Ni:Al molar ratios, Al 2 O 3 supports and preparation methods were synthesized. The suitability of the catalysts was analyzed considering activity, stability and carbon yield. Catalysts showed a good performance and similar results according to syngas compositions were obtained.However, some differences related to stability over time and carbon yields were detected. TPR analysis and TEM micrographs of the fresh catalysts revealed the presence of two different Ni particles: large Ni particles with low metal support interaction (MSI) that favoured the formation of encapsulating carbon and small Ni particles inserted in the Al 2 O 3 structure with a greater MSI that lead to NCs formation.Generally both kinds of Ni particles were observed in all catalysts, however their relative abundance was dramatically affected by the Al 2 O 3 employed, the preparation method and the Ni:Al molar ratio.
