  2. 1. The low-carbon steel industry - Interactions between the hydrogen direct reduction of steel and the electricity system

    Author : Alla Toktarova; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Renewable Energy; Energy systems modelling; Hydrogen-direct reduction; Steel industry; Electrification;

    Abstract : The European steel industry must achieve deep reductions in CO2 emissions to meet the targets set out in the Paris Agreement. Options for reducing CO2 emissions include electrification, carbon capture and storage (CCS) and the use of biomass. READ MORE

  4. 2. Planning production and supply chain in energy intensive process industries

    Author : Martin Waldemarsson; Helene Lidestam; Martin Rudberg; Magnus Karlsson; Sophie D'Amours; Linköpings universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process industry; Energy-intensive production processes; Energy system; Energy management; Production planning; Supply chain planning; Case studies; Mixed Integer Linear Programming; Modelling; Specialty chemicals; Pulp; Steel;

    Abstract : To make a difference among the energy intensive process industries, this dissertation addresses production planning and supply chain planning problems related to industrial energy management issues. The energy issue is turning more and more important from different angles, involving price as well as environmental problems due to climate change leading to political pressure on all energy users.

    Abstract : The manufacturing industry represents a highly important sector of the Swedish economy. The increasing demands placed on the quality and performance of products that are manufactured places increasing demands on the manufacturing processes involved. READ MORE

  6. 4. Modeling of phase transformations and cyclic plasticity in pearlitic steels

    Author : Björn Andersson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Phase transformations; TRIP; Pearlitic steel; FEM; Cyclic plasticity; Homogenization;

    Abstract : The low rolling resistance in railway transportation is a key factor for its high efficiency, but it comes at the price of very high contact pressure between the rail and wheel. Due to the high stresses and the large number of load cycles during railway operation, both the rail and the wheel can be susceptible to fatigue crack initiation and propagation. READ MORE

  7. 5. Structural Modifications in Spruce Wood during Steam Explosion Pretreatment

    Author : Muhammad Muzamal; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mechanical property; X-ray tomography; Spruce wood; Steam explosion; Finite element model; Physical structure; Enzymatic hydrolysis;

    Abstract : The rising price of petroleum and environmental concerns regarding CO2 emissions have 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 valueadded chemicals. READ MORE
