5. 3. Structured Nanoporous Materials for Biogas Upgrading

   Author : Kritika Narang Landström; Farid Akhtar; Andreas Kaiser; George Shimizu; Marta-Lena Antti; Manuel Moliner Marín; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nanoporous materials; biogas upgrading; zeolites; metal-organic framework; carbon capture; separation kinetics; Materialteknik; Engineering Materials;

   Abstract : Porous materials have shown potential for solving one of the significant challenges to sequestering CO2 gas from point sources. Microporous materials, zeolites and metal-organic frameworks (MOFs) are porous materials with tailorable adsorptive properties to develop higher performance for an energy-efficient CO2 separation.

6. 4. Sustainable production of bio-energy products in the sawmill industry

   Author : Anna Vidlund; KTH; []
   Keywords : sawmill industry; energy efficiency; heat recovery; integration; biofuel; upgrading; district heating; fuel pellets; CHP; VOC; CO2;

   Abstract : One of the great challenges facing society is to convert theglobal energy system to a sustainable process. Currently, 80%of the world´s energy is supplied through the combustionof fossil fuels. Not only are the fossil resources limited, theutilisation also increases the level of greenhouse gases in theatmosphere. READ MORE

7. 5. Catalytic valorization of lignocellulose : Direct and sidestream upgrading approaches

   Author : Davide Di Francesco; Joseph Samec; Orlando Rojas; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Lignin; biomass; catalytic fractionation; dearomatization; heterogeneous catalysis; organisk kemi; Organic Chemistry;

   Abstract : This work aims to explore different approaches for the valorization of lignocellulosic biomass. In this regard, two different strategies are presented: the catalytic upgrading of lignocellulose derivatives from industrial streams, such as pyrolytic oil and kraft lignin, and the direct catalytic fractionation of woody biomass.
