  1. 6. Point source carbon capture by porous inorganic carbonates

    University essay from Uppsala universitet/Nanoteknologi och funktionella material

    Author : Jonas Hultberg; [2018]
    Keywords : Carbon capture; Gas separation; Adsorbent; Inorganic carbonates; Point source; Carbon dioxide; Kolavskiljning; Adsorbenter; Oorganiska karbonater; Punktkälla; Koldioxid;

    Abstract : Mesoporous inorganic carbonates (MIC) was synthesized and tested as adsorbents for CO2, using vacuum and temperature swing adsorption. Mesoporous magnesium carbonate (MMC), mesoporous calcium carbonate (MCC) and mesoporous calcium magnesium carbonate (MCMC), all included in MIC, are exceedingly porous with an amorphous structure.

  3. 7. Application of sorption-enhanced catalysis to ethanol reforming

    University essay from KTH/Skolan för kemivetenskap (CHE)

    Author : Jacky Ho; [2016]
    Keywords : Catalysis; adsorption; Li4SiO4; CaO; Ethanol reforming;

    Abstract : Lithium orthosilicate (Li4SiO4) is known to be a high temperature CO2 capture material. This work was focused on comparing Li4SiO4 to the extensively studied CaO as an adsorbent in sorption enhanced catalysis. Thermogravimetric analysis was used to study the effects of sorption temperature and compaction on Li4SiO4 using 15vol% CO2 in N2. READ MORE

  4. 8. Structure and reactivity of surface oxides on Cu(100)

    University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Author : Benjamin Hagman; [2016]
    Keywords : Cu 100 ; STM; Missing row reconstruction; XPS; Reverse water-gas shift; Physics and Astronomy;

    Abstract : Adsorption of oxygen onto Cu(100) leads to formation of a well-ordered surface structure known as the `missing row' (MR) reconstruction. The aim of the work described in this thesis was to characterize the chemical properties of this MR structure, which serves as a well-defined analogue for oxidized copper surfaces used in catalysis for CO2 hydrogenation.

  5. 9. Upgrading of Landfill Gas with Household Waste Slag

    University essay from KTH/Skolan för kemivetenskap (CHE)

    Author : Seyedhani Sadatgol; [2015]
    Keywords : Landfill gas; Hydrogen sulfide; Bottom Ash; Carbonation; Slag;

    Abstract : Modern landfills produce landfill gas, LFG, on a smaller scale and with limited content of degradable organic materials in the waste. The waste deposit in the Sofielund landfill began in 2005 and the final coverage is not yet commenced. The landfill waste must contain up to 10% decomposable organic materials at most. READ MORE

  6. 10. Atomic Scale Design of Graphene based Gas Sensors

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Nandini Patra; [2014]
    Keywords : ;

    Abstract : In this project work, we have performed Density Functional Theory (DFT) calculations to study the gas (CO, NO and CO2) sensing mechanism of pure and doped (B, N and B-N) graphenesurfaces. Generalized gradient approximation (GGA-PBE) within projector-augmented  wave (PAW) methodology were adopted to investigate the electronic properties  of such materials. READ MORE
