Biogas to Syngas through the Combined Steam/Dry Reforming Process: An Environmental Impact Assessment

The combined steam/dry reforming (S/DR) technology was used to produce syngas from clean biogas. In the reaction conditions proposed, catalytic bed can produce, without deactivation, a with H2/CO ratio of ?2 directly processable for methanol or Fischer–Tropsch syntheses. Starting laboratory data obtained in industrial conditions, mass and energy balances overall process were Aspen HYSYS simulations. environmental evaluation performed by applying life cycle assessment (LCA) methodology, comparing different scenarios current route (autothermal ATR natural gas). analysis showed that biogas-to-syngas using processes has potential reduce anthropogenic impact on environment. ReCiPe method when S/DR is conducted biogas also as heat source, CO2 balance turns negative, ensuring whole excellent carbon capture utilization (CCU) providing lowest damage all categories. Its improvement would make it possible further burden process, which essential achieving sustainable development.
