  1. 1. An Investigation of Market Scalability for Volatile Organic Compounds (VOCs') Filtration Systems : A Case Study within Sweden

    Master-uppsats, Uppsala universitet/Industriell teknik

    Författare :Chaitanya Sai Praneeth Kurukundu; Anvesh Reddy Gajjala; [2020]
    Nyckelord :Volatile Organic Compounds; Formaldehyde; Activated carbon; Thermal sintering; Impregnated catalyst; Efficiency; Indoor Air Quality; Filtration Systems;

    Sammanfattning : With the need for excellent living standards to escalate day by day, the need to breathe good quality air remains of paramount importance for a prosperous, happy life. The indoor air quality picture is improving decade by decade. However, the importance of maintaining good indoor air quality remains unsatisfactory. LÄS MER

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

    Master-uppsats, KTH/Skolan för kemivetenskap (CHE)

    Författare :Jacky Ho; [2016]
    Nyckelord :Catalysis; adsorption; Li4SiO4; CaO; Ethanol reforming;

    Sammanfattning : 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. LÄS MER

  4. 3. µHDS system for desulfurization of logistic fuels for fuel cell applications

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Johan Karstensson; Nicklas Jönsson; [2016]
    Nyckelord :Jet fuel; DBT; thiophene; HDS; catalysis; kemiteknik; chemical engineering; Jet A1; Technology and Engineering;

    Sammanfattning : Logistic fuels such as diesel and petrol, in which Jet A1 is included, are sulfur-containing fuels used for transports. The main problem with logistic fuels, when used in fuel cell (FC) applications, is their relatively high concentration of sulfur compounds. LÄS MER

  5. 4. Katalytisk tjärreformering i förgasning av biomassa

    Master-uppsats, KTH/Skolan för kemivetenskap (CHE)

    Författare :OLOF FORSBERG; [2015]
    Nyckelord :;

    Sammanfattning : Gasification of biomass is today facing several problems with the high amount of tar produced and compounds such as alkali that can harm the catalyst in catalytic tar reformation. This is why the focus in this master thesis study was to create a catalyst for secondary tar steam reforming. LÄS MER

  7. 5. Investigation on the Use of Intermediate Crops for Anaerobic Digestion as a Renewable Source of Energy

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Ida Ahlberg; Thais Leidiomara Silva Nilsson; [2015]
    Nyckelord :biofuels; pretreatment; acetic acid; steam pretreatment; sodium hydroxide; kemiteknik; chemical engineering; Mellangrödor; Hemp; White mustard; Oilseed radish; Sudangrass; Hairy vetch; Phacelia; energy; Intermediate crops; Biogas; Anaerobic digestion; Agriculture and Food Sciences; Earth and Environmental Sciences; Biology and Life Sciences; Technology and Engineering; Chemistry;

    Sammanfattning : The eminent dilemma around the relationship between the increasing world population, the need of new fuel sources and environment issues has raised great awareness in the last decades. The European Parliament has set common goals such as the reduction of the greenhouse gases by 20 % by the year of 2020, followed by the requirement of at least 10 % of the fuel has to be biofuel.
