  1. 1. Effect of powder spray drying on catalyst formulation in tablet form

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Kajsa Wahlgren; [2023]
    Nyckelord :Spray dryer; Catalyst; Powder; Flowability; Chemical engineering; Technology and Engineering;

    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

  3. 2. Investigation of Cu and Zn interactions with ilmenite during waste incineration

    H-uppsats,

    Författare :Elin Borgman; [2020-06-08]
    Nyckelord :FactSage; copper; zinc; major ash elements;

    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).

  4. 3. Groundwater denitrification by fluidized bioelectrochemical systems

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Lena Bonin; [2020]
    Nyckelord :Bioelectrochemistry; fluidized bed reactor; bioremediation; denitrification; groundwater; reduced graphene oxide;

    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

  5. 4. Värmeöverföring mellan två zoner i en bubblande fluidiserad bädd

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Christian Stigsson; [2018]
    Nyckelord :Heat transfer; fluidized beds; multi-staging; Eulerian-Eulerian two-fluid; Technology and Engineering;

    Sammanfattning : 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.

  7. 5. Influence of Potassium on Gasification Performance

    Master-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Hepa Rasol; [2016]
    Nyckelord :Biomass; pyrolysis; steam and CO2 gasification; fluidized bed reactor; alkali metals; reaction rate; reactivity; GC- MS; TGA; bio- char and bio- tar;

    Sammanfattning : 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.
