Subcritical water - a perspective reaction media for biomass processing to chemicalsPavlovič, Irena (Avtor) Knez, Željko (Avtor) Škerget, Mojca (Avtor) celulozabiomasasubkritična vodahidrotermana konverzijabiooljaBiomass and water are recognized as a key renewable feedstock in sustainable production of chemicals, fuels and energy. Subcritical water (SubCW), or commonly referred as hot compressed water (HCW), is the water above boiling and below critical point (CP; 374 °C, 22.1 MPa). It has gained great attentionin the last few decades as a green, cheap, and nontoxic reagent for conversion of biomass into valuable chemicals. In this paper, hydrothermal reactions of cellulose, as the model biomass substance, with subcritical waterat mild temperature and pressure regimes have been studied. The experiments were done in a batch reactor in the temperature range of 220 ° - 300 °C. The main products distributed in liquid, gaseous and solid phase were separated and quantified. The conversions to each group of products were foundstrongly dependent on the temperature and residence time.20132015-07-10 12:38:57Delo ni kategorizirano50363UDK: 544.7OceCobissID: 16830230COBISS_ID: 16830486ISSN pri članku: 0352-9568NUK URN: URN:SI:UM:DK:RBY8U0ETsl
