Simulated pollutant formation trends in the oxyfuel combustion of biogenic gases with water injection

An integrated pilot plant producing carbon-negative advanced biofuels ◼ Pyrolysis process ◼ Biomass as feedstock ◼ Advanced biofuels: - Hydrogen (H 2), e-methane, pyrolysis oil ◼ Certified biochar carbon sink Feedstock ◼ Four biogenic feedstocks − Prunings, wood, digestate, hops offcuts ◼ High sulfur and nitrogen content possible Pyrolysis and gas treatment ◼ TCR (Thermo-Catalytic Reforming) ◼ Gas treatment: - Ammonia (NH 3) reduced to 400 ppm - Hydrogen Sulfide (H 2 S) reduced to 100 ppm ◼ H 2 separation with VPSA (Vacuum Pressure Swing Adsorption)
