Regions with important wood industries offer two potentially underestimated resource types: forestry residue biomass (FRB) and waste wood (WW). Although these materials are widely available (approx. 130mio. m3a-1 FRB, approx. 50mio. ta-1 WW in the EU), they are mostly valorised through energy production, as they are high in ashes and may be contaminated with organics and heavy metals. In this study, both FRB and WW were treated via one-step pyrolysis for AC production. ZnCl2 was applied as activating agent at pyrolysis temperatures varying from 400 to 600 °C and residence times between 1 and 3 h. Overall, 76 samples were prepared and characterized thoroughly via elemental analysis, N2/CO2 ad/-desorption, thermogravimetric analysis (TGA), scanning electron microscopy (SEM), and infrared spectroscopy (FTIR). The produced carbons showed specific surface areas of up to 1430m2g−1 and a pore size distribution with a micropore share of up to 80 %. The presence of oxygen-containing functional groups was confirmed via FTIR. Potential feedstock contamination can be mitigated, as minerals and heavy metals could be leached out (up to –99.15 %) by an additional wash step and organic contamination undergoes thermal cracking during pyrolysis.

The results demonstrate that this S-ATDRM system can achieve an exergy efficiency of 84.7 %, and about 1055.7 kW of exergy can be recuperated from the process for crude syngas cooling and reapplied for pre-heating of feedstocks of CO2, O2 and CH4. It is found that the largest exergy destruction in this system occurs in the partial oxidation reactor, which occupies ca. 45.6 % of the whole exergy loss.
