  2. 1. Ethanol Pulping of Reed Canary Grass

    Author : Helena Håkansson; Karlstads universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Pulping; Nonwood plants; Reed canary grass; Ethanol; Organosolv pulping; Statistical analysis; Chemical Engineering; Kemiteknik;

    Abstract : The aim of this study was to investigate the possibility of processing an agricultural crop grown in Sweden to usable pulp. A further purpose was to study ethanol pulping applied to a non-wood raw material.The first part of this thesis deals with the criteria for selecting a fibre crop for further studies. READ MORE

  5. 3. Valorization of low-value lignocellulosic side-streams

    Author : Daria Lebedeva; Joseph S. M. Samec; Emiel J.M. Hensen; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Lignocellulose; lignin; hemicellulose; hydrodeoxygenation; zeolites; furfural; catalysis; cycloaddition; biomass fractionation; pulping; Organic Chemistry; organisk kemi;

    Abstract : The development of novel pathways for valorizing low-value streams from pulp, forest, and agricultural industries is crucial for realizing a circular bioeconomy and addressing the needs of both platform chemicals and fuels. Utilizing hemicellulose and lignin as biomass-derived feedstocks facilitates the production of sustainable liquid hydrocarbons, with catalytic hydrodeoxygenation being a key process. READ MORE

  6. 4. Palladium-catalyzed lignin valorization : Towards a lignin-based biorefinery

    Author : Maxim Galkin; Joseph Samec; Rafael Luque; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Lignin; Heterogeneous Catalysis; Palladium; Biomass; Depolymerization; Reduction; Oxidation; Biorefinery; Transfer Hydrogenolysis; Organic Chemistry; Organisk kemi;

    Abstract : The work described in this thesis focuses on the cleavage of the β-O-4′ bond, which is the most abundant interunit linkage in the lignin polymer.In the first part, three methods based on palladium catalysis have been developed and their applicability has been verified using lignin model compounds.

  7. 5. Production and transformation of organic compounds from renewable feedstock : Catalytic approaches

    Author : Elena Subbotina; Joseph Samec; Pieter Bruijnincx; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Lignin; biomass; lignin-first; catalytic fractionation; flow reactors; dibenzodioxocin; silanes; zeolites; visible light photocatalysis; dearomatization; spirolactones; organisk kemi; Organic Chemistry;

    Abstract : This thesis is focused on the development of strategies for lignocellulosic biomass valorization. The thesis consists of two parts.The first part of the presented work is related to the catalytic fractionation of biomass (lignin-first approach) and the production of monomeric compounds from lignocellulose.
