1. 1. Steam Explosion of Wood

   Författare :Muhammad Muzamal; Chalmers University of Technology; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; finite element model; Steam explosion; biorefinery; pretreatment; wood;

   Sammanfattning : The rising price of petroleum and environmental concerns regarding CO2 emissions has increased interest in alternative renewable resources. Biomass can be considered as an excellent alternative raw material. A biorefinery uses biomass and produces fuel, energy and value-added chemicals. LÄS MER

3. 2. Recalcitrance of wood to biochemical conversion : feedstock properties, pretreatment, saccharification, and fermentability

   Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; LANTBRUKSVETENSKAPER; ENGINEERING AND TECHNOLOGY; AGRICULTURAL SCIENCES; Recalcitrance; Pretreatment; Enzymatic saccharification; Ionic liquid; Steam explosion; Enzyme inhibition; Non-productive binding; Microbial inhibitors;

   Sammanfattning : Lignocellulose is an inexpensive and abundant renewable resource that can be used to produce advanced biofuels, green chemicals, and other bio-based products. Pretreatment and efficient enzymatic saccharification are essential features of bioconversion of lignocellulosic biomass. LÄS MER

4. 3. Ethanol from Softwood - Process Development Based on Steam Pretreatment and SSF

   Författare :Kerstin Stenberg; Institutionen för kemiteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; economy; infection; inhibition; recirculation; S. cerevisiae; SSF; steam pretreatment; ethanol production; process development; softwood; Carbochemistry; petrochemistry; fuels and explosives technology; Petrokemi; bränslen; sprängämnen;

   Sammanfattning : Fuel ethanol can be produced from lignocellulosics by the enzymatic hydrolysis process, which consists of a pretreatment step prior to hydrolysis, followed by fermentation and finally refining. This thesis deals with the development of the enzymatic process using softwood as raw material. LÄS MER

5. 4. Process development and environmental assessment within softwood based biorefineries

   Författare :Karin Carlqvist; Institutionen för kemiteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sugar platform; extractives; steam explosion; pretreatment; bark; enzymatic hydrolysis; phenolic compounds; bioeconomy; LCA; Pinus sylvestris; Picea abies; pine; spruce; sockerplattform; extraktivämnen; Steam explosion SE ; förbehandling lignocellulosa; bark; enzymatisk hydrolys; fenoler; bioekonomi; LCA; Pinus sylvestris; Picea abies; tall; gran;

   Sammanfattning : We urgently need to move from a fossil-based to a bio-based society. From a Swedish perspective, a promising way forward are biorefineries with an integrated production of materials, chemicals, and energy from the softwood species Scots pine (Pinus sylvestris) and Norway spruce (Picea abies).

7. 5. Development of the Steam Pretreatment Process for Production of Ethanol from Lignocellulosic Biomass

   Författare :Sanam Monavari; Bioteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Spruce; Ethanol production; Sugarcane bagasse; SSF; Fermentation; Enzymatic hydrolysis; SO2; Steam pretreatment; Acid catalyst;

   Sammanfattning : At a time when natural petroleum resources are on the verge of depletion, and concern about climate change is increasing, the potential of lignocellulosic material for the production of bioethanol is well recognized. Ethanol can be produced from biomass through enzymatic hydrolysis and fermentation. LÄS MER
