  1. 1. Chemical characterization in the biorefinery of lignocellulose : Formation and management of oxalic acid and analysis of feedstocks for bioethanol production

    University dissertation from Karlstad : Karlstads universitet

    Author : Anders Sjöde; Karlstads universitet.; [2008]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICINE Chemistry Biochemistry; MEDICIN Kemi Biokemi; Kemi; Chemistry; biorefinery; enzymes; ethanol; lignocellulosic feedstocks; oxalic acid; scaling;

    Abstract : The pulp and paper industry is entering a new era. Pulp mills will be transformed to biorefineries that produce not only pulp, but also biofuels and novel products from lignocellulose. This thesis addresses problems connected with the industrial transition to environmental-friendly technologies and the implementation of the biorefinery concept. READ MORE

  2. 2. Biochemical conversion of biomass to biofuels pretreatment–detoxification–hydrolysis–fermentation

    University dissertation from Umeå : Umeå universitet

    Author : Venkata Prabhakar Soudham; Umeå universitet.; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lignocellulosic materials; Ionic liquids; Pretreatment; Inhibitors; Detoxification; Ferrous sulfate and hydrogen peroxide; reducing agents; alkaline treatments; Hydrolysis; Fermentation; Biofuels; biokemi; Biochemistry;

    Abstract : The use of lignocellulosic materials to replace fossil resources for the industrial production of fuels, chemicals, and materials is increasing. The carbohydrate composition of lignocellulose (i.e. cellulose and hemicellulose) is an abundant source of sugars. READ MORE

  3. 3. Conversion of Biomass to Renewable Liquid Feedstocks in Pyrolysis-based Applications

    University dissertation from KTH Royal Institute of Technology

    Author : Henry Persson; KTH.; [2019]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Pyrolysis; Biomass; Pre-treatment; Stepwise Pyrolysis; Catalytic Pyrolysis; Pyrolys; Biomassa; Förbehandling; Stegvis Pyrolys; Katalytisk Pyrolys; Materials Science and Engineering; Teknisk materialvetenskap;

    Abstract : The production of chemicals and fuels currently rely on fossil resources which are associated with global warming as well as economic and political instabilities. The demand for renewable alternatives is increasing as legislations on greenhouse gas emissions are becoming more stringent. READ MORE

  4. 4. Bioethanol Production from Lignocellulosic Materials: Some studies on Sugarcane Bagasse and Paja Brava

    University dissertation from Lund University

    Author : Cristhian Carrasco; Lund University.; Lunds universitet.; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Paja Brava Sugarcane Bagasse Saccharomyces cerevisiae Pichia stipitis;

    Abstract : The commercial feasibility of ethanol production from biomass is dependent on the availability of lignocellulose in large amounts at low cost. Various kinds of agricultural residues are of interest, due to the fact that these feedstocks have well-established cultivation procedures already in place, as well as technology for harvest and transportation.
