BioROBURplus builds upon the closing FCH JU BioROBUR project (direct biogas oxidative steam reformer) to develop an entire pre-commercial fuel processor delivering 50 Nm3/h (i.e. 107 kg/d) of 99.9% hydrogen from different biogas types (landfill gas, anaerobic digestion of organic wastes, anaerobic digestion of wastewater-treatment sludges) in a cost-effective manner. The energy efficiency of biogas conversion into H2 will exceed 80% on a HHV basis, due to the following main innovations: 1) increased internal heat recovery enabling minimisation of air feed to the reformer based on structured cellular ceramics coated with stable and easily recyclable noble metal catalysts with enhanced coking resistance; 2) a tailored pressure-temperature-swing adsorption (PTSA) capable of exploiting both pressure and low T heat recovery from the processor to drive H2 separation from CO2 and N2; 3) a recuperative burner based on cellular ceramics capable of exploiting the low enthalpy PTSA-off-gas to provide the heat needed at points 1 and 2 above. The complementary innovations already developed in BioROBUR (advanced modulating air-steam feed control system for coke growth control; catalytic trap hosting WGS functionality and allowing decomposition of incomplete reforming products; etc.) will allow to fully achieve the project objectives within the stringent budget and time constraints set by the call.
