Abstract:
The integration of a solid-fuel production and a biogas plant allows the use of wet municipal biomass for thermal use, after leaching and mechanical dewatering of the biomass, e.g. practiced at Eigenbetrieb Umwelttechnik of the city of Baden-Baden, Germany. The used biomasses are fresh biowaste and green cut waste preserved by ensiling. In this paper, it was determined whether or not the leached and dried solid fuel is suitable for utilization in the bioliq process. For this investigation, fast pyrolysis experiments were carried out with samples from the press cake of green cut waste and biowaste in a laboratory scale fluidized bed reactor at 500°C. For the water-free feedstock a condensate yield of up to 47 mass% and a solid content of - 32 mass% was determined. The solid and liquid products of the green cut waste contained up to 94 % of the energy content from the starting material. The pyrolysis products are chemically similar to those of other biomasses, except for a distinctive share of fatty acids due to the variability of the feedstock. The results show that the use of these leached and dried waste materials in the context of the bioliq process is possible.
