6. Efficiency and Selectivity in the Chlorate Process
Sammanfattning : This licentiate thesis presents experimental studies concerning two parts of the electrochemical cell in the chlorate process: a cathode and an anode.Newly synthesized MnOx electrodes were investigated for the cathodic reaction, hydrogen evolution reaction (HER) in the chlorate process.

7. Selectivity and gas composition in electrochemical systems by mass spectrometry
Sammanfattning : This doctoral thesis presents experimental studies of gaseous products of two electrochemical systems: the chlorate process and the nickel-metal hydride (NiMH) battery, employing mass spectrometry.The cathodic efficiency for the hydrogen evolution reaction (HER) of the chlorate process was investigated by employing ex-situ synthesized MnOx electrodes.

8. The High Temperature Corrosion of Alloy Sanicro 28
Sammanfattning : This thesis investigates the influence of potassium chloride in solid and gaseous form on the oxidation of alloy Sanicro 28 (35Fe27Cr31Ni). KCl induced corrosion of chromia forming alloys is important e.g. in fireside corrosion in biomass and waste fired power plants. LÄS MER
9. High Temperature Corrosion of Some Stainless Steels
Sammanfattning : The high temperature corrosion of the alloy Sanicro 28 (35Fe27Cr31Ni) is addressed in this thesis. The influence of water vapour and two potassium-containing salts was investigated. In addition, three other alloys were studied. Polished steel coupons were isothermally exposed in tube furnaces at 600–800°C in 5% O2 and in 5% O2 + 40% H2O. LÄS MER
