Fractionation of Flash Pyrolysis Condensates by Staged Condensation

The utilization of condensates from flash pyrolysis is challenging due to several unwanted properties. The condensates consist of a mixture of many high value compounds, but each of them is only contained in a low concentration. As additional challenge instantaneous phase separation into an aqueous and a sludgy heavy organic phase takes place, if agricultural residues like barley straw are used as raw material for pyrolysis. A separation by means of distillation is not possible as the compounds undergo polymerization reactions when exposed to higher temperature. A different approach for separation based on boiling temperature is staged condensation of original vapors. Ablative flash pyrolysis is performed in a laboratory. The pyrolysis vapors are condensed in either two or three stages, each composed of a double-effect cooler followed by an electrostatic precipitator. The higher boiling fractions are low in water and acid and show a high heating value

Mapping of samples – Fuels from Reliable Bio-based Refinery Intermediates: BioMates, Schulzke et al., 2020, DOI:10.1007/s12649-019-00625-w

In the H2020-project BioMates (www.biomates.eu, Grant Agreement No. 727463), Fraunhofer UMSICHT produced samples from ablative fast pyrolysis (AFP) of herbaceous biomass in a TRL 4-plant. A dedicated document provides identifiers for relevant liquid samples and their blends (DOI: 10.24406/fordatis/156). The document at hand maps it to the AFP-derived substances reported to be used in the article "T. Schulzke, S. Conrad, B. Shumeiko, M. Auersvald, D. Kubička, L. F. J. M. Raymakers; Fuels from Reliable Bio-based Refinery Intermediates: BioMates; Waste and Biomass Valorization (2020) 11:579–598; DOI:10.1007/s12649-019-00625-w", and provides further identifiers for samples not indexed earlier.Read with: Adobe Acrobat Reade

Potential GHG reduction and reduction cost of combined heat and power production by gasification of various biomass feedstock

According to Directive 2009/28/EC (EU RED) a comprehensive study was performed to determine the potential greenhouse gas (GHG) reduction for the combined production of heat and power from solid biomass via gasification. The potential GHG reduction of biomass conversion to electricity (and heat) ranges from around 550 g/kWhel without heat utilization to 841 g/kWhel with complete heat utilization. For the commercial scale (5 to 10 MW fuel input) the reduction costs range from about 200 /t CO2-equivalent without heat utilization to around 80 /t with heat utilization. These values can be compared to reduction costs of other processes for electricity production from renewable sources: the reduction costs for photovoltaic energy are around 850 /t; for wind energy, around 125 /t; for hydro po wer, around 30 /t and for biogas plants with anaerobic digestion, between 200 and 290 /t, depending on heat utilization. To sum up, it can be determined that combined heat and power production from solid (residual) biomass by autothermal gasification can greatly contribute to the aim of the German government to reduce the GHG emissions by 20 % by 2020 and that this reduction can be achieved at competitive costs

Ablative Fast Pyrolysis (AFP) is the first step in the BioMates-concept to convert herbaceous biomass into co-feed with reliable properties for conventional refineries (www.biomates.eu). The document defines samples and sample blends produced by Fraunhofer UMSICHT via AFP within the H2020-project BioMates.Adobe Acrobat Reade

Ablative Fast Pyrolysis - Process for valorization of residual biomass: Presentation held at 5th International Conference on Chemical Technology, 10.-12.04.2017, Mikulov, Tschechische Republik

The direct use of pyrolysis condensates is hindered by unwanted properties of the liquid, especially if herbaceous biomass is used. Ablative fast pyrolysis simplifies the conversion process as no heat carrier material is necessary and for herbaceous biomass briquetting can be applied instead of energy-intensive grinding. To avoid phase separation of the primary liquid product staged condensation can be applied. Pyrolysis condensates collected as fractions from three-staged condensation can be used for energetic applications (bunker fuel or heavy heating oil) on one side but also as substitute for fossil resources in phenol-formaldehyde resins as adhesives in wood industry or polyurethane foams in sandwich boards for building insulation
