  1. 1. Analytical Pyrolysis - Studies of Sulfur in Coal and Pulp

    University dissertation from Analytical Chemistry, Lund University

    Author : Pernille Selsbo; [1996]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; sulfur; pulp; PLS; PCA; fractionated pyrolysis; FPD; analytical pyrolysis; coal; Analytical chemistry; Analytisk kemi;

    Abstract : Sulfur in coal and pulp have been characterized using pyrolysis–gas chromatography with a sulfur-selective flame photometric detector (Py–GC/FPD). The samples (50–150 µg) were pyrolyzed at temperatures between 300 and 1400°C usually followed by a combustion in oxygen at high temperature (>1000°C). READ MORE

  2. 2. Coal, commerce and communism : Empirical studies on energy history in the Czech Republic

    University dissertation from Lund University (Media-Tryck)

    Author : Hana Nielsen; Lunds universitet.; Lund University.; [2017-03-24]
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; industrialization; coal; modern economic growth; central planning; iron and steel; energy efficiency;

    Abstract : This thesis employs an international comparative perspective to empirically analyse the Czech energy transition between 1830 and 2010. It addresses the utilization of energy in shaping modern economic growth through structural and technological change and the implications of those changes on specialization and foreign trade.

  3. 3. Coal and Oil: The Dark Monarchs of Global Energy Understanding Supply and Extraction Patterns and their Importance for Future Production

    University dissertation from Uppsala : Acta Acta Universitatis Upsaliensis

    Author : Mikael Höök; Uppsala universitet.; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; oil production; coal production; depletion rate; forecasting; energy supply; NATURAL SCIENCES Physics; NATURVETENSKAP Fysik; NATURAL SCIENCES Earth sciences Other earth sciences; NATURVETENSKAP Geovetenskap Övrig geovetenskap; TECHNOLOGY Industrial engineering and economy Physical planning; TEKNIKVETENSKAP Industriell teknik och ekonomi Fysisk planläggning; TECHNOLOGY Engineering physics Other engineering physics; TEKNIKVETENSKAP Teknisk fysik Övrig teknisk fysik; Physics with specialization in Global Energy Resources; Fysik med inriktning mot globala energiresurser;

    Abstract : The formation of modern society has been dominated by coal and oil, and together these two fossil fuels account for nearly two thirds of all primary energy used by mankind.  This makes future production a key question for future social development and this thesis attempts to answer whether it is possible to rely on an assumption of ever increasing production of coal and oil.

  4. 4. Biocarbon for fossil coal replacement

    University dissertation from Luleå : Luleå University of Technology

    Author : Aekjuthon Phounglamcheik; Luleå tekniska universitet.; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biomass pyrolysis; charcoal; bio-oil recycling; CO2 utilization; reactivity; rotary drum; Energiteknik; Energy Engineering;

    Abstract : This research aims to provide a full view of knowledge in charcoal production for fossil coal replacement. Charcoal from biomass is a promising material to replace fossil coal, which is using as heating source or reactant in the industrial sector. READ MORE

  5. 5. Capture of CO2 from solid fuels using Chemical-Looping Combustion and Chemical-Looping Oxygen Uncoupling

    University dissertation from Luleå : Luleå University of Technology

    Author : Henrik Leion; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; chemical-looping with oxygen uncoupling; fluidized bed; gasification; CO2-capture; biofuels; oxygen carrier; chemical looping combustion; CLOU; petroleum coke; coal; CLC;

    Abstract : In order to meet the global demand of CO2 neutral energy, chemical-looping combustion could play an important role. Oxygen can be transferred from the combustion air to the fuel by means of oxygen carrying metal oxide particles circulating between two reactors, an air- and a fuel reactor. READ MORE
