  1. 1. Mitigating Knock in Heavy Duty Spark Ignition Engines : Experiments and simulations of diluted ethanol and methanol combustion

    Author : Senthil Krishnan Mahendar; Anders Christiansen Erlandsson; Christer Spiegelberg; James Szybist; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ethanol; Methanol; Dilution; Spark Ignition; Miller Timing; Machine Design; Maskinkonstruktion;

    Abstract : To effectively reduce fossil fuel dependence in the transport sector, an unprecedented increase in renewable fuel production is required. Short chain alcohols, such as ethanol and methanol, are well placed as they can be produced in a variety of renewable pathways from most carbon sources. READ MORE

  2. 2. Characterization of the Combustion of Light Alcohols in CI Engines : Performance, Combustion Characteristics and Emissions

    Author : Sam Shamun; Förbränningsmotorer; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Methanol; Ethanol; Oxygenated Fuel Blends; Compression Ignition Engine; Partially Premixed Combustion; Combustion Characteristics; Efficiency; Emissions; Particulate Matter; Metanol; Etanl; Oxygenerade Bränsleblandningar; Kompressionsantänd Motor; Partiellt Förblandad Förbränning; Förbränningsegenskaper; Verkningsgrad; Emissioner; Partiklar;

    Abstract : Alternative fuels for combustion engines are becoming increasingly popular as society is pushing to phase out fossil energy to reduce CO2 emissions. The compression ignition (CI) engine has a high overall efficiency which makes it a valuable option for the transport fleet, despite the well known NOx and soot pollutants it emits. READ MORE

  3. 3. Development and application of new chiral -amino alcohols in synthesis and catalysis : Use of 2-azanorboryl-3-methanols as common intermediates in synthesis and catalysis

    Author : Pedro Pinho; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Asymmetric synthesis; hetero-Diels-Alder reactions; chiral cyclopentyl-amines; chiral ligands and catalysts; amino alcohols; asymmetric reductions; ruthenium transfer hydrogenation; oxazaborolidines; asymmetric additions; dialkylzinc reagents; Kemi; Chemistry; Kemi; organisk kemi; Organic Chemistry;

    Abstract : The development and application of unnatural amino alcohols,prepared via hetero-Diels-Alder reactions,in synthesis and catalysis is described.The studies are concerned with the [i]scope of the hetero-Diels-Alder reaction and preparation of important intermediates in the synthesis of antiviral agents,[ii ]application of amino alcohols in the ruthenium transfer hydrogenation of ketones,[iii ]use of similar precursors in the in situ generation of oxazaborolidines for reduction of ketones,and [iv] development and application of new chiral auxiliaries for dialkylzinc additions to activated imines, respectively.

  4. 4. Catalytic conversion of syngas to higher alcohols over MoS2-based catalysts

    Author : Robert Andersson; Magali Boutonnet; Sven Järås; Anders Holmen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; conversion; higher alcohols; mixed alcohols; MoS2; syngas; Chemical Engineering; Kemiteknik;

    Abstract : The present thesis concerns catalytic conversion of syngas (H2+ CO) into a blend of methanol and higher alcohols, an attractive way of producing fuels and chemicals. This route has the potential to reduce the oil dependence in the transport sector and, with the use of biomass for the syngas generation, produce CO2-neutral fuels. READ MORE

  5. 5. Identification of principal chemical subsets of biofuel combustion : Ants walking in renewable fire

    Author : Christoffer Pichler; Förbränningsfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Reduced kinetic models; Biofuel; n-Heptane; Alcohols; Ant-Colony Reduction; Combustion chemistry; Fysicumarkivet A:2020:Pichler;

    Abstract : The work in this thesis was carried out to highlight important chemical pathways in skeletal mechanisms for the three smallest alcohol fuels (methanol, ethanol and npropanol), two representative fuel alkanes n-heptane and n-decane, and finally the biodiesel surrogates, methyl-decanoate, methyl-5-decenoate, and methyl-9-decenoate. This aim was set up to further the efforts of creating Computational Fluid Dynamics (CFD) suitable mechanisms, which in turn can be used by the industry to improve, for example, engines or gas turbines, or by academia to further understand turbulent combustion.
