The study on application of biopolyols obtained by cellulose biomass liquefaction performed with crude glycerol for the synthesis of rigid polyurethane foams
PublicationIn this work rigid polyurethane foams (PUR) were obtained by replacement of 0–70 wt% of petrochemical polyol with bio-polyol obtained via cellulose liquefaction in presence of crude glycerol. The foams with different content of a bio-polyol were prepared by single step method for NCO/OH ratio equals 1.5. The prepared materials were analyzed in terms of their morphology, chemical structure, thermal stability and basic physical and...

Podniesienie sprawności konwersji energii biomasy poprzez termiczno-chemiczną pirolizę w biopaliwa ciekle i gazowe
PublicationProduktem termicznego rozkładu biomasy jest biowęgiel, biopaliwa ciekłe i palny gaz (wodny, generatorowy). Dzięki zwiększonej gęstości energii w tych przetworzonych biopaliwach ich transport, magazynowanie i dalsze przetwarzanie jest ekonomicznie i ekologicznie bardziej opłacalne, niż surowej biomasy, która jest lekka i ma małą kaloryczność. Zaprezentowane w niniejszym opracowaniu metody przetwarzania biomasy w energię użyteczną...

Chemical structures, rheological and physical properties of biopolyols prepared via solvothermal liquefaction of Enteromorpha and Zostera marina biomass
PublicationIn this work, liquefied biomass from the Baltic Sea was used for the preparation of rigid polyurethane (PUR) foams. The biomass contained 10 wt% of Enteromorpha macroalgae and 90 wt% of Zostera marina seagrass characterized by a high content of cellulose. The influence of time, temperature and the type of solvent on the efficiency of the liquefaction process and properties of biopolyols was determined. Obtained materials were analyzed...

Study on the Structure-Property Dependences of Rigid PUR-PIR Foams Obtained from Marine Biomass-Based Biopolyol
PublicationThe paper describes the preparation and characterization of rigid polyurethane-polyisocyanurate (PUR-PIR) foams obtained with biopolyol synthesized in the process of liquefaction of biomass from the Baltic Sea. The obtained foams differed in the content of biopolyol in polyol mixture (0–30 wt%) and the isocyanate index (IISO = 200, 250, and 300). The prepared foams were characterized in terms of processing parameters (processing...

Microstructure–Property Relationship of Polyurethane Foams Modified with Baltic Sea Biomass: Microcomputed Tomography vs. Scanning Electron Microscopy
PublicationIn this paper, novel rigid polyurethane foams modified with Baltic Sea biomass were compared with traditional petro-based polyurethane foam as reference sample. A special attention was focused on complex studies of microstructure, which was visualized and measured in 3D with high-resolution microcomputed tomography (microCT) and, as commonly applied for this purpose, scanning electron microscopy (SEM). The impact of pore volume,...

Termiczno-chemiczna piroliza do biopaliw ciekłych i gazowych, jako metoda podnoszenia sprawności konwersji energii biomasy
PublicationW pracy opisano i sklasyfikowano wybrane metody przetwarzania biomasy w biopaliwa ciekłe i gazowe. Skupiono się na bardziej zaawansowanych technologicznie rozwiązaniach uznając, iż bezpośrednie spalanie biomasy w celu wyprodukowania energii termicznej, w porównaniu z innymi sposobami konwersji jest ekonomicznie najmniej opłacalne.

Sustainable Strategy for Algae Biomass Waste Management via Development of Novel Bio-Based Thermoplastic Polyurethane Elastomers Composites
PublicationThis work concerns the waste management method of algae biomass wastes (ABW). For this purpose, we prepared bio-based thermoplastic polyurethane elastomer (bio-TPU) composites. Algae biomass wastes are derived from algal oil extraction of Chlorella vulgaris and from biomass of Enteromorpha and Zostera marina. ABWs were used in the bio-TPUs composites as a filler in the quantity of 1, 5, 10, and 15 wt.%. The bio-based composites...
