Valorization potential of technical lignins from Norway spruce (Picea abies) via pyrolysis

Autor: Maryam Ghalibaf, Raimo Alén, Idoia Hita, Peter J. Deuss, Hero Jan Heeres, Paul de Wild

Publikováno v: Journal of Analytical and Applied Pyrolysis, 165:105549. ELSEVIER SCIENCE BV

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 potential of these mate

Effect of Tire-Char Ash on the Extent of Synergy during CO2 Cogasification with Hydrochar from Potassium-Rich Coconut Fiber

Autor: Reza Khoshbouy, Fumitake Takahashi, Saleem Ullah, Douglas Hungwe, Kunio Yoshikawa, Lu Ding

Publikováno v: Energy & Fuels. 34:8110-8119

The influence of inherent tire char ash during co-gasification with coconut hydrochar prepared at different intensities was investigated by thermogravimetric analysis to ascertain the extent to which synergistic interaction, reactivity, and activatio

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

Autor: Lempiäinen, Henna, Lappalainen, Katja, Mikola, Marja, Tuuttila, Tero, Hu, Tao, Lassi, Ulla

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 for hydrolysis (100 °C, 60

Tuotekosteuden hallinta biomassan kuivauksessa

Autor: Vepsä, Juha

Useimmat biomassan jalostusprosessit, mm. kaasutus ja pyrolysointi, edellyttävät biomassan kuivaamista tietylle tasolle. Näissä prosesseissa käytettävät biomassan kuivaimet ovat pääosin jatkuvatoimisia. Tämän työn tarkoituksena oli tutkia
