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

    University essay from Lunds universitet/Kemiteknik (CI)

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

    Abstract : 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. READ MORE

  3. 2. Study of Reverse Water Gas Shift reaction using bimetallic catalysts on active supports : The case of unpromoted and K-promoted FeCu/CeO2

    University essay from KTH/Kemiteknik

    Author : Carlo Sala; [2022]
    Keywords : CO2 utilization; RWGS; catalyst; active catalytic support; characterization; CO2 användning; RWGS; katalysator; aktiva katalysatorbärare; karakterisering;

    Abstract : Reverse Water Gas Shift Reaction (RWGS) är en attraktiv lösning för CO2-använding och minskning av utsläppen i atmosfären. Denna reaktion begränsas av termodynamiken och det finns problem med storskalig tillämpning. För att förbättra genomförandet av processen krävs utveckling av en effektiv katalysator. READ MORE

  4. 3. Investigation into the Removal of the By-product NDMA (N-Nitrosodimethylamine) from Ozonation Process in Wastewater Treatment

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Zehao Li; [2021]
    Keywords : Water resources engineering; Ozonation; NDMA; Wastewater; pharmaceutical; Diclofenac; Ibuprofen; Naproxen; Technology and Engineering;

    Abstract : In people’s modern life, daily usage of artificial compounds such as active pharmaceuticals ingredients (API) is usual. These compounds are likely to end up as micropollutants in the municipal wastewater. Municipal wastewater is the major source of pharmaceuticals in the aquatic environment. READ MORE

  5. 4. Groundwater denitrification by fluidized bioelectrochemical systems

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

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

    Abstract : 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. READ MORE

  6. 5. Modelling of Biomass Pyrolysis with Ex-situ Catalytic Upgrading for Bio-crude Production

    University essay from KTH/Materialvetenskap

    Author : Febryana Nugrahany; [2018]
    Keywords : ex-situ catalytic upgrading; slow pyrolysis; screw reactor; fixed bed catalytic reactor; process design;

    Abstract : This study presents a techno-economic assessment of slow pyrolysis of pine sawdust continued by ex-situ catalytic upgrading. The overall process consists of six sections: feed drying, pyrolysis, vapor filtration, ex-situ catalytic upgrading, vapor quenching, and combustion of permanent gas. READ MORE
