2. 6. Pyrolysis of mixed plastics and paper to produce fuels and other chemicals

   Author : Nanta Sophonrat; Weihong Yang; Linda Sandström; Tobias Richards; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Pyrolysis; Mixed plastics and biomass; Cellulose; Refuse derived fuels RDF ; Paper rejects; Interactions; Stepwise pyrolysis; Calcium oxide CaO ; Chemical Engineering; Kemiteknik; Energy Technology; Energiteknik;

   Abstract : As the world population and economy grow, higher consumption results in higher waste packaging, plastics and paper residues. Pyrolysis offers a way to recover fuels and other chemicals from this waste fraction. READ MORE

4. 7. Kinetic investigations of combustion of small oxygenated aliphatic hydrocarbons – modeling and experiments

   Author : Gianluca Capriolo; Förbränningsfysik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kinetic modelling; Nitric Oxide; n-propanol; i-propanol; propanal; LIF; Fysicumarkivet A:2020:Capriolo;

   Abstract : The depletion of oil reserves and the increasingly stringent European Union regulation of air pollution have forced researchers and manufacturers to search for cleaner and sustainable substitutes to petroleum‐based transportation fuels. Biofuels like small aliphatic alcohols are of increasing interest as alternatives to fossil fuels, as they offer long‐term fuel‐source regenerability. READ MORE

5. 8. Lean NOx reduction by alternative fuels - with focus on catalysts for dimethyl ether

   Author : Sara U Erkfeldt; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; biofuel; In2O3; lean NOx reduction; alumina; Cu-ZSM-5; Ga2O3; DME; hydrocarbon-SCR; alternative fuel; NOx storage; B2O3; Ag Al2O3;

   Abstract : There is an increased demand for diesel engines running on non-fossil fuels such as dimethyl ether (DME), biodiesel and synthetic diesel. DME is a promising alternative fuel with potential for high energy efficiency and low CO2 emissions. However, during all high temperature combustion NOx is formed, which may require exhaust aftertreatment. READ MORE

6. 9. Experimental Studies on Using Butanol and Octanol Isomers as Drop-in Fuels for Diesel Engines

   Author : Tankai Zhang; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : The increasing importance of transportation in modern societies has caused fossil fuel consumption to increase greatly in recent decades. However, burning fossil fuels in internal combustion engines can lead to high emissions of greenhouse gases, which cause climate change. READ MORE

7. 10. 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
