We present simulation results for the production of algae-derived hydrogen and syngas using a dual fluidized bed (DFB) gasifier. A global sensitivity analysis is performed to determine the impact of key process parameters (i.e. gasification temperature, feed water content, steam to biomass ratio, and air equivalence ratio) on the product yield and cold gas efficiency. Also, in order to account for different algae strains and varying extents of oil extraction prior to the gasification process the algae oil content was varied from 0 to 40 wt%. The results presented here can help to benchmark gasification against other algae conversion strategies in terms of process efficiency, feasibility and impact on the environment. |
