1. Effect of powder spray drying on catalyst formulation in tablet form
Master-uppsats, Lunds universitet/Kemiteknik (CI)Sammanfattning : Heterogenous catalysts consist of a large surface area support material applied with the catalytic active phase, and the activity of a catalyst is often correlated to the surface area per volume. Support materials often need to be processed further to be optimal for specific processes. LÄS MER
2. Investigation of Cu and Zn interactions with ilmenite during waste incineration
H-uppsats,Sammanfattning : In 2018, approximately 2.01 billion tons of waste was generated in the world. By 2050, this number is expected to increase drastically to 3.40 billion tons of waste annually as lower income countries develop and the world population increases (Kaz, Yao, BhadaTata, & Van-Woerden, 2018).

3. Groundwater denitrification by fluidized bioelectrochemical systems
Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)Sammanfattning : Groundwater (GW) accounting for most of the freshwater available around the World, finding sustainable techniques to depollute it is of crucial importance for safe drinking water supply. The extensive use of fertilizers in the agriculture, as well as other anthropogenic activities, are contributing to the excessive nitrate levels in some aquifers. LÄS MER
4. Värmeöverföring mellan två zoner i en bubblande fluidiserad bädd
Master-uppsats, Lunds universitet/Institutionen för energivetenskaperSammanfattning : In this Master's thesis, the heat transfer between two zones in a bubbling fluidized bed and the resultant temperature field were examined using a laminar Eulerian-Eulerian two-fluid model in computational fluid dynamics. The purpose was to estimate the thermal potential to multi-stage a combined heat and power boiler by integration therein of a communicating gasification reactor, which utilizes heat from the combustion, and to analyze how different construction parameters influence the homogeneity of the gas temperature field.

5. Influence of Potassium on Gasification Performance
Master-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomiSammanfattning : To release energy from chemically stored energy in the biomass was the new investigation in recent years. Utilizing of biomass for this purpose occur in two different ways, directly by burning (combustion) the biomass and indirectly by pyrolysis process which will convert the biomass to three main products, bio- tar, bio- char and synthetic gas.
