  2. 1. High temperature corrosion during waste incineration : characterisation, causes and prevention of chlorine-induced corrosion

    Author : Peter Viklund; Christofer Leygraf; Jan Froitzheim; Staffan Hertzman; Sweden Stockholm Swerea KIMAB AB; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; high temperature corrosion; waste incineration; superheater tubing; steel; alkali; chlorine; suphur; Chemistry; Kemi;

    Abstract : Waste-fired boilers suffer severely from corrosion of critical components such as superheater tubes. In this work the high temperature corrosion of candidate superheater alloys have been investigated by detailed laboratory studies and controlled field exposures in full-scale boilers. READ MORE

  4. 2. Towards a responsive functional material: Modification of porosity and grafting of poly(N-isopropylacrylamide) in mesoporous silica SBA-15

    Author : Nina Reichhardt; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; mesoporous silica; SBA-15; intrawall pores; PNIPAAM; lower critical solution temperature; water sorption calorimetry; gas sorption;

    Abstract : Mesoporous silica materials, such as SBA-15, have potential as biocompatible carriers for pharmaceutical applications as well as mini-reactors in e.g. catalysis. This potential arises from their well-defined porous structure on the nanometre scale accompanied by a high internal surface area (800 - 1000 m2/g). READ MORE

  5. 3. High Temperature Corrosion Behavior in Biomass- and Waste-Fired Boilers - Insights into catastrophic corrosion and corrosion mitigation techniques

    Author : Julien Phother Simon; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 3D tomography; TEM; Sulfur Recirculation; Waste; High-temperature corrosion; Biomass; Coatings; Stainless steel; Ni-based alloys; Deposits; KCl-induced corrosion;

    Abstract : Carbon dioxide is contributing to the greenhouse effect and a significant part comes from the use of fossil fuels. Utilizing more renewable fuels is therefore a solution to decrease the net release of CO2 emissions to the atmosphere. READ MORE

  6. 4. High Temperature Corrosion of Superheaters in Biomass - and Waste-Fired Boilers: Combat on two fronts

    Author : Julien Phother Simon; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stainless steel; KCl; Deposits; Waste; Oxidation; Biomass; Ni-based coatings;

    Abstract : Carbon dioxide is a greenhouse gas contributing to the greenhouse effect and a significant contribution comes from the use of fossil fuels. Utilizing more renewable fuels is therefore a solution to decrease the net release of CO2 emissions to the atmosphere. READ MORE

  7. 5. Ethyl(hydroxyethyl)cellulose and Some Model Uncharged Polymers: A Calorimetric Study of Their Interaction with Surfactants in Aqueous Solution

    Author : Geng Wang; Biokemi och Strukturbiologi; []
