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

    University dissertation from Department of Chemical Engineering, Lund University

    Author : Elisabeth Joelsson; Lunds universitet.; Lund University.; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biorefinery; distillers dried grain with solubles; 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

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

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Abraham Judah Bumalirivu Muwanguzi; KTH.; [2013]
    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
