• 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 ...

• Acid-catalyzed mechanocatalytic pretreatment to improve sugar release from birch sawdust : Structural and chemical aspects 

  Lempiäinen, Henna; Lappalainen, Katja; Mikola, Marja; Tuuttila, Tero; Hu, Tao; Lassi, Ulla (Elsevier BV, 2022)

  This study examined acid-catalyzed mechanocatalytic pretreatment of birch sawdust without a separate impregnation step. Catalyst amount and pretreatment time were the key variables. Pretreated material was mixed with water ...

• Chemical Characterization of Okra Stalk (Abelmoschus esculentus) as Potential Raw Material for Biorefinery Utilization 

  Ullah, Saleem; Kilpeläinen, Petri; Ilvesniemi, Hannu; Pakkanen, Hannu; Alén, Raimo (Editura Academiei Române, 2018)

  In the present work, okra stalk (Abelmoschus esculentus) was chemically characterized to evaluate its appropriate exploitation as a biorefinery feedstock. The chemical composition of this renewable lignocellulosic material ...

• Brønsted and Lewis acid catalyzed conversion of pulp industry waste biomass to levulinic acid 

  Lappalainen, Katja; Kuorikoski, Eveliina; Vanvyve, Elise; Dong, Yue; Kärkkäinen, Johanna; Niemelä, Matti; Lassi, Ulla (Department of Forest Biomaterials, North Carolina State University, 2019)

  Enormous amounts of fiber sludge are generated annually by the pulp industry as a by-product. As a cellulose-rich material, its current usage, mainly as fuel, is inefficient from a material efficiency point of view. This ...

• Analytical pyrolysis of wood and non-wood materials from integrated biorefinery concepts 

  Ghalibaf, Maryam (2019)

  Wood and non-wood differ with respect to their anatomical, physical, and chemical properties, even among their species, resulting in different behaviors during thermal conversion. Hence, understanding the degradation ...
