2. 1. Synthesis gas from black liquor : trace components and methanol synthesis

   Author : Caroline Häggström; Mats Lindblom; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical Technology; Kemisk teknologi;

   Abstract : The common European Energy and Climate policy states that in 2020 the share of biofuels for inland transports should be 10 %. Such a stipulation calls for a commercially sustainable biofuel production. READ MORE

4. 2. Absolute Asymmetric Synthesis

   Author : Anders Lennartson; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; absolute asymmetric synthesis; enantioselective synthesis; chirality; optical resolution; spontaneous resolution; conglomerate; organozinc reagents; organometallic chemistry; coordination chemistry; supramolecular chemistry; intermolecular interactions; optical resolution;

   Abstract : Absolute asymmetric synthesis is the synthesis of optically active products from achiral or racemic precursors only. This has generally been regarded as impossible and is relevant in the discussion of the origins of biomolecular homochirality. READ MORE

5. 3. CO2 activation for methanol synthesis on copper and indium oxide surfaces

   Author : Alvaro Posada Borbon; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Methanol conversion; Heterogeneous catalysis; Density functional theory; Copper surface; Indium oxide​​; CO2 reduction;

   Abstract : Catalytic recycling of CO2 to added-value chemicals, such as methanol (CH3OH), has been proposed as a possible way for sustainable production of fuel and chemicals, in addition to providing a route to mitigate climate change. Multiple systems are known to be active for the conversion of CO2 to methanol, and the state of the art catalyst is Cu/ZnO/Al2O3. READ MORE

6. 4. 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.

7. 5. Catalytic conversion of biomass-derived synthesis gas to liquid fuels

   Author : Rodrigo Suárez París; Magali Boutonnet; Agustín Martínez Feliu; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biofuels; Fischer-Tropsch wax; higher alcohols; hydroconversion; kinetic modelling; methanol cofeeding; microemulsion; MoS2; noble metal; syngas; Chemical Engineering; Kemiteknik;

   Abstract : Climate change is one of the biggest global threats of the 21st century. Fossil fuels constitute by far the most important energy source for transportation and the different governments are starting to take action to promote the use of cleaner fuels. READ MORE
