Worldwide, a large amount of biomass accumulates in the form of ligno-cellulosic agricultural by-products that can neither be efficiently used as animal feed nor as feedstock for anaerobic digestion. A clean and energy-efficient utilization in combustion plants is counter-indicated by high contents of elements like Cl, K and Na that decrease the ash-melting-point and lead to fouling and corrosion. Although this biomass is, therefore, not suitable for conventional combustion plants, a pyrolysis process can be applied that works at lower temperatures of 500-600°C.
