| Abstract Scope |
Hydrogen and synfuels obtained from biomass by thermal conversion processes can offer a cost-efficient alternative compared to such from direct water electrolysis. In general most types of biomass can contain increased levels of chlorine which is even aggravated if marine biomass is taken into account which can be available in abundant quantities in some coastal areas in Europe but also world-wide. When considering energetic exploitation of the latter in thermal conversation processes specific material challenges may arise in the respective plants resulting from the increased chlorine levels in such type of biomass. High temperature chlorine corrosion requires material approaches that take into account the specific type of mechanisms of this kind of attack including the formation of gaseous (and potentially liquid) corrosion products with the respective consequences for thermodynamic and kinetic considerations. These will be described in conjunction with recommendations for material selection under such conditions. |
