Applicability of Torrefied Sunflower Husk Pellets in Small and Medium Scale Furnaces
Kienzl N, Margaritis N, Isemin R, Zaychenko V, Strasser C, Kourkoumpas DS, Grammelis P, Klimov D, Larina O, Sytchev G, Mikhalev A. Applicability of Torrefied Sunflower Husk Pellets in Small and Medium Scale. Waste and Biomass Valorization. 2020;275:122882.
The aim of this paper is to test the applicability of upgraded agricultural biomass feedstock such as torrefied sunflower husks during combustion in small and medium heating applications. Sunflower husk is formed in large quantities at enterprises producing sunflower oil and can be used as biofuel. However, big problems arise due to the low bulk density of husks and the rapid growth of ash deposits on the heating surfaces of boilers. In order to solve these problems, it was proposed to produce pellets from husks, and to subject these pellets to torrefaction. After torrefaction, net calorific value was increased by 29% while the risk of high temperature corrosion of boilers was reduced. Signs of ash softening neither occurred in combustion of raw nor in combustion of torrefied sunflower husk pellets. High aerosol emissions, already present in raw sunflower husk pellets, could not be mitigated by torrefaction. First combustion results at medium scale furnaces indicated that sunflower husk pellets (both raw and torrefied) in a commercial boiler < 400 kW, operated in a mode with low primary zone temperatures (< 850 °C), meet current emission limits. Regarding the future upcoming emission limits according to the European Medium Combustion Plant Directive, additional measures are required in order to comply with the dust limits.

The Contribution of advanced renewable transport fuels to transport decarbonisation in 2030 and beyond
Bacovsky D, Laurikko J. The Contribution of advanced renewable transport fuels to transport decarbonisation in 2030 and beyond. 28th European Biomass Conference and Exhibition (oral presentation) 2020.
In the light of climate change, there is an urgent need to decarbonize our societies. The transport sector is specifically challenging, as transport demand is still growing, and so are the sector´s GHG emissions. Several countries have set ambitious national targets for GHG reduction in the transport sector. These are often backed with policy measures for implementation of both advanced renewable transport fuels and electrification.
In a project set up jointly by two Technology Collaboration Programmes of the International Energy Agency, namely the IEA Bioenergy TCP and the Advanced Motor Fuels TCP, the contribution that advanced renewable transport fuels should make to the decarbonisation of the transport sector is assessed by means of country-specific assessments.

Machbarkeitsuntersuchung Methan aus Biomasse
Im Rahmen dieser zusammenfassenden Machbarkeitsstudie werden Untersuchungen zum Biomassepotential in Österreich im Jahr 2050 sowie der Synthese von BioSNG auf Basis der Biomassewirbelschichtvergasung durchgeführt. Dabei werden verschiedene Vergasungsverfahren, welche durch den Reaktortyp charakterisiert sind, dargestellt. Bedingt durch das homogene Temperaturprofil, welches in einem Wirbelschichtvergaser gegeben ist und die dadurch gegebene einfache Regelbarkeit des Prozesses, stellt sich die Wirbelschicht als vorteilhaft im Vergleich zu Flugstromvergasern dar, welche durch das hohe Temperaturniveau einen höheren technischen Aufwand mit sich bringen und daher für Anlagen mit großen Brennstoffwärmeleistungen zu bevorzugen sind. In weiterer Folge wird auf den DFB Prozess und dessen Weiterentwicklung, den G-Volution Vergaser eingegangen, welcher den Vorteil eines größeren einzusetzenden Brennstoffspektrums aufweist.
