2. 1. Techno-economic evaluation of integrated lignocellulosic ethanol production

   Author : Elisabeth Joelsson; Avdelningen för kemiteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; distillers dried grain with solubles; biorefinery; modelling; Aspen Plus; biogas; logging residues; spruce; wheat straw; wheat grain; heat; integration; pinch analysis; techno-economic evaluation; first generation; second generation; Ethanol; Lignocellulosic material;

   Abstract : Sweden has claimed that it wants to have a fossil-free vehicle fleet in 2030 as a milestone of its ambitious goal for 2050 to be a country with a sustainable and resource-efficient energy supply without any net GHG emissions. Production of bioethanol from plant materials is one potential method of meeting this goal. READ MORE

4. 2. Investigating the parameters that influence the behaviour of natural iron ores during the iron production process

   Author : Abraham Judah Bumalirivu Muwanguzi; Andrey V Karasev; Henrik Saxèn; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; natural iron ore; iron production; characterization; physical and metallurgical properties; sinter; pellet; direct reduction; low temperature degradation; sample weight; sample positioning; microstructure; reduction degree; solid conversion; Volumetric Model; Grain Model; Random Pore Model; Muko; Uganda;

   Abstract : In the iron production processes, sinters and pellets are mostly used as raw materials due to their consistency with respect to physical and chemical properties. However, natural iron ores, as mined, are rarely used directly as a feed material for iron processing. READ MORE

6. 4. Unlocking the Potential of Brewer’s Spent Grain : Sustainable Biorefinery Approach and Value-Added Product Generation

   Author : Mohsen Parchami; Mohammad J Taherzadeh; Sudip Rakshit; Högskolan i Borås; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Brewer s spent grain; Hydrothermal pretreatment; Organosolv pretreatment; Edible filamentous fungi; Anaerobic digestion; Biorefinery; Resource Recovery; Resursåtervinning;

   Abstract : Brewer’s spent grain (BSG) constitutes 85% of brewing byproducts and 30% of initial malt. In 2021, BSG production reached approximately 37.2 million tons. Owing to its high moisture and nutritional content, BSG is prone to biological deterioration, causing environmental issues when discarded as waste. READ MORE

7. 5. On deoxidation practice and grain size of austenitic manganese steel

   Author : Dimitrios Siafakas; Anders Jarfors; Taishi Matsushita; Johan Nils Ahlström; Jönköping University; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hadfield steel; deoxidation; grain size; inoculation; particles; carbides; oxides; Hadfield stål; desoxidering; kornstorlek; ympning; partiklar; karbider; oxider;

   Abstract : The exceptional wear resistance and work hardenability, place Hadfield steel as one of themost important materials for manufacturing cast components used in the mining, crashing,drilling, and excavation industries. In all metallic alloys used for component casting, themechanical properties are highly influenced by the microstructure of the material. READ MORE
