In April, Bio4Fuels subproject 4, Gasification Processes, published an article titled “Experimental and simulation studies of oxygen-blown, steam-injected, entrained flow gasification of lignin”.
The findings show that increased reactor temperature enhances H2 and CO production. Higher steam-to biomass ratios increased the H2 and reduced the CO production, as well as improving the cold gas (CGE) and the carbon conversion (CCE) efficiencies. Larger particles and increasing amounts of O2, decrease the CO and the H2 production. Simulations reveal that the optimal air/fuel ratio range for steam injection is between 0.15–0.35. A sensitivity analysis highlights the significant impact of reactor temperature on H2 and CO production. While the air/fuel ratio shows high sensitivity for H2 production, the steam-to biomass ratio exerts a greater impact on CO production.
