  1. 1. Modeling and Control of the Open Plate Reactor

    Författare :Staffan Haugwitz; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; process control; process intensification; heat exchange reactor; mid-ranging control; extended Kalman filter; model predictive control;

    Sammanfattning : The focus of this thesis is on modeling and control of the Open Plate Reactor (OPR), a new heat exchange reactor being developed by Alfa Laval AB. It combines intensified mixing with enhanced heat transfer capacity into one operation. LÄS MER

  3. 2. System Simulation of Partially Premixed Combustion in Heavy-Duty Engines : Gas Exchange, Fuels and In-cylinder Analysis

    Författare :Erik Svensson; Förbränningsmotorer; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Partially Premixed Combustion PPC ; Compression ignition; Direct injection; Methanol; Engine optimization; Stochastic reactor model; T-phi diagrams; Partially premixed combustion; Compression Ignition; Direct Injection; Methanol; Engine Optimization; Stochastic reactor model; Gas exchange; T-phi diagrams;

    Sammanfattning : The concept of partially premixed combustion (PPC), applied to conventional diesel engines, has shown to yield high gross efficiencies and low emissions of oxides of nitrogen and soot. PPC emerged from the knowledge gained from homogeneous charge compression ignition (HCCI) research. LÄS MER

  4. 3. Small-Scale Production of Fuel-Cell Hydrogen

    Författare :Christian Hulteberg; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydrogen; Chemical Engineering; Catalysis; Small-Scale;

    Sammanfattning : The work presented here aims at producing hydrogen for proton-exchange fuel-cell applications from hydrocarbons. This thesis describes an integrated catalytic converter comprising a steam-reforming reactor (heat of reaction supplied by catalytic combustion), a water-gas shift reactor and a preferential oxidation of carbon monoxide reactor, and the work performed on the fuel processing catalysts therein.

  5. 4. Thermally homogenous gasification of biomass/coal/waste for medium or high calorific value syngas production

    Författare :Anna Ponzio; Wlodzimierz Blasiak; Petr Stehlik; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Metallurgical process engineering; Metallurgisk processteknik;

    Sammanfattning :  Today’s problems with emissions of green house gases, land filling of waste and depletion of the oil reserves calls for new energy systems based on alternative fuels like biomass and waste. Gasification is an attractive technology for the use of such solid fuels. LÄS MER
