1. 16. High temperature corrosion in biomass-fired energy applications : Alloying effects and test environment comparisons

   Författare :Ragna Elger; Rachel Pettersson; Inger Odnevall Wallinder; Rikard Norling; Gordon Tatlock; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; High temperature corrosion; biomass; waste; superheater corrosion; austenitic steel; biomass gasification; alumina-forming austenitic stainless steel; thermodynamic modelling; kinetic modelling; Kemi; Chemistry;

   Sammanfattning : To reduce the greenhouse effect, the use of renewable fuel has to be increased. As renewable fuel has different characteristics compared to fossil fuel regarding content of trace metals, alkali, chlorine and sulphur, the corrosion characteristics in high temperature energy processes have to be evaluated.

3. 17. Kinetic investigations of combustion of small oxygenated aliphatic hydrocarbons – modeling and experiments

   Författare :Gianluca Capriolo; Förbränningsfysik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kinetic modelling; Nitric Oxide; n-propanol; i-propanol; propanal; LIF; Fysicumarkivet A:2020:Capriolo;

   Sammanfattning : The depletion of oil reserves and the increasingly stringent European Union regulation of air pollution have forced researchers and manufacturers to search for cleaner and sustainable substitutes to petroleum‐based transportation fuels. Biofuels like small aliphatic alcohols are of increasing interest as alternatives to fossil fuels, as they offer long‐term fuel‐source regenerability. LÄS MER

4. 18. Investigation of Solid Fuel Conversion in a Fluidised Bed Gasifier – Modelling and Experiments

   Författare :Louise Lundberg; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; modelling; biomass; char reactivity; gasification; char conversion; fluidised bed;

   Sammanfattning : A substantial proportion of Sweden’s greenhouse gas emissions originates from the transportation sector, and the Swedish government has set the goal that the entire Swedish vehicle fleet will be independent from fossil fuels by 2030. One of the strategies investigated to achieve this goal is biomass gasification, which is a technology that can be used to transform lignocellulosic materials into a raw gas. LÄS MER

5. 19. FEM Modelling of Micro-galvanic Corrosion in Al Alloys Induced by Intermetallic Particles : Exploration of Chemical and Geometrical Effects

   Författare :Litao Yin; Jinshan Pan; Christopher Leygraf; Ying Jin; Herman Terryn; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Finite Element Method FEM ; Modelling; Micro-galvanic corrosion; Al alloy; corrosion product deposition; chemical factors; steric hindrance effect; Kemi; Chemistry;

   Sammanfattning : Localized corrosion, such as pitting, crevice corrosion or galvanic corrosion, is a long-standing phenomenon that can greatly limit the life of metallic materials. For decades experimental methods have been used to try to understand the underlying physical, chemical and electrochemical processes that control localized corrosion in order to find effective protection methods against its propagation.
