By the regulation for facilitating the feed-in of natural gas made of biomass [GasnetzzugangsV] in the currently existing natural gas grid, which was passed by the German Bundeskabinett in 2008, an important general framework was set for the preferential and cost-efficient feed-in of natural gas made of biomass. In order to be fed-in the biogas has to meet the requirements of the process sheets G 260 and G 262 of the “Deutsche Vereinigung des Gas- und Wasserfachs e.V.”, i.e. the biogas is to be refined to natural gas grade. In order to achieve the required gas quality, desulphurization is an important process step. During desulphurization hydrogen sulphide (H2S) is removed from the gas. This purification is essential for the biogas quality, since corrosion damage to the natural gas piping due to H2S has to be avoided. The H2S level in the biogas must not exceed 5 mg/m³. In order to meet these requirements two desulphurization stages are necessary: the first “coarse” stage removes the main part of H2S down to about 50 – 100 mg/m³; the second “fine” stage is needed especially for achieving natural gas quality. Especially for the latter process step a cost-efficient purification system, which ensures compliance of the thresholds during the time of operation, is inevitable.
In the joint research project an innovative purification system consisting of a metal foam as carrier structure and a sorbent suitable for desulphurization (Fe2O3) will be developed and the verification of its applicability for the “fine” stage of desulphurization will be made, i.e. the compliance with the threshold of 5 mg/m³ and the regeneration of the sorbent will be evaluated. The goal is to achieve significant improvements in energy- and cost-efficiency compared to the current state-of-the-art in the “fine” stage of desulphurization.
