AbstractTraditionally, biogas has been considered a non-value by-product which was generally burned in flares. Most recently, different alternatives for biogas utilization have been proposed such as heat, electricity or bio-methane production. However, from an economical point of view, the aforementioned applications depend on government feed in tariff and therefore renewable energy producers face an unstable scenario. For that reason, the production of new products from biogas is not only interesting but necessary to diminish the profitability barriers. In that context, the simultaneous production of syngas and carbon nanofilaments is proposed (Figure 1). One the one hand, syngas constitutes the base of the C1 chemistry and depending on its H2:CO ratio it can be used to produce methanol, dimethyl ether, liquid hydrocarbons or H2. On the other hand, carbon nanofilaments are high added value material due totheir unique properties (thermal and electricity conductivity and textural properties) that make them a promising material as catalyst support, synthetic graphite or graphene precursor or additive in polymer composites. This process, in which syngas and carbon nanofilaments are simultaneously produced from biogas, has been studied for the first time during the course of this thesis and it has been named “Catalytic Decomposition of Biogas (CDB)”. Thus, the purpose of the thesis work was to study the technical viability of the biogas valorisation through catalytic decomposition to obtain syngas and high added value carbon nanofilaments.
