Sulfur-free pulping of hot-water-extracted spruce sawdust
Lehto, Joni; Alén, Raimo; Kleen, Marjatta (Mid Sweden University, 2016)Softwood (Picea abies) sawdust was hot-water-extracted with two multi-phase processes (160-180°C, 100-280 min, and liquor-to-wood ratio 5 l/kg) corresponding to P-factors of ~780 (yield 80.0%) and ~4580 (yield 72.4%). The ... -
Valorization potential of technical lignins from Norway spruce (Picea abies) via pyrolysis
Ghalibaf, Maryam; Alén, Raimo; Hita, Idoia; Deuss, Peter J.; Heeres, Hero Jan; de Wild, Paul (Elsevier BV, 2022)Analytical pyrolysis (Py-GC/MS) on mg-scale of Norway spruce (Picea abies)-derived kraft lignin, ethanosolv lignin, and dried lignin-rich soda-anthraquinone (AQ) black liquors was studied at 500 °C to compare the valorization ... -
Advanced biorefinery concepts related to non-wood feedstocks
Ullah, Saleem (University of Jyväskylä, 2018)Agricultural residues, such as wheat straw (Triticum aestivum), okra stalk (Abelmoschus esculentus), and giant miscanthus (Miscanthus × giganteus, a hybrid of M. sinensis and M. sacchariflorus) were investigated to ... -
Combustion Properties of Birch (Betula pendula) Black Liquors From Sulfur-Free Pulping
Chen, Chengcong; Alén, Raimo; Lehto, Joni; Pakkanen, Hannu (Taylor & Francis Inc., 2016)Sulfur-free pulping has an environmental advantage over the traditional kraft process. This article describes the combustion properties of the black liquors produced from silver birch (Betula pendula) sawdust using three ... -
Combustion properties of spruce black liquor droplets : Sulfur-free pulping and influence of hot-water pretreatment
Chen, Chengcong; Alén, Raimo; Lehto, Joni; Pakkanen, Hannu (Svenska Pappers- och Cellulosaingenioersfoereningen, 2016)Hot-water pretreatment of lignocellulosics prior to sulfur-free alkaline pulping is an interesting approach for recovering value-added carbohydrate- and lignin-derived materials. This paper investigated the chemical ...
