  2. 21. Aspects of Efficient Parameter Estimation for Diesel Oxidation Catalysts

    Author : Björn Lundberg; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MVDA; Mass Transport Modeling; Engine Test Bench; Design of Experiments; Kinetic modeling; DOC; Full Scale; Parameter Estimation; Exhaust Aftertreatment Modeling;

    Abstract : In this thesis the objective was to tune the model parameters of diesel oxidation catalysts (DOC) to measurement data from engine rig experiments in an efficient manner. The scope was however not limited to the algorithm of parameter search alone but instead included the whole process starting with the design of experiments. READ MORE

  4. 22. High flux zeolite membranes for efficient production of biofuels

    Author : Linda Sandström; Hannes Richter; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical Technology; Kemisk teknologi;

    Abstract : The greenhouse effect and the limited fossil oil resources have increased the demand for renewable fuels. Zeolite membranes have potential applications in numerous separation processes, and could be useful in the development of efficient processes for renewable fuel production. READ MORE

  5. 23. Integration of thermochemical processes with existing waste management industries to enhance biomethane production

    Author : Chaudhary Awais Salman; Jinyue Yan; Eva Thorin; Yang Weihong; Mälardalens högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; polygeneration; process integration; integrated biorefineries; biomethane; Energy- and Environmental Engineering; energi- och miljöteknik;

    Abstract : In most waste management industries, waste is separated into different fractions, each of which is treated with suitable processes. Established technologies such as waste combustion for combined heat and power (CHP) production and biomethane production through anaerobic digestion (AD) of biodegradable waste work fine as standalone processes.

  6. 24. Biogas from agricultural waste : Turning unavailable residues into accessible resources

    Author : Mirjam Victorin; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biogas; Straw; Manure; Pretreatment; Process design;

    Abstract : Moving from a fossil dependent to a fossil free economy requires increased energy production from renewable resources. This thesis discusses the utilization of agricultural waste streams, such as straw and manure, for biogas production. READ MORE

  7. 25. Biomass Gasification-Based Biorefineries in Pulp and Paper Mills – Greenhouse Gas Emission Implications and Economic Performance

    Author : Johan Isaksson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biorefinery; heat integration; energy efficiency; CO2 emissions; process integration; pulp and paper mill; biomass gasification;

    Abstract : The pulp and paper industry has a great opportunity to take advantage of the experience about forestry and wood handling for production of renewable fuels, chemicals and materials. Residues from forestry, i.e., tops, branches and stubs, have great potential to become a raw material that can replace crude oil or natural gas in many applications. READ MORE
