  4. 2. Catalytic valorization of lignocellulose : Direct and sidestream upgrading approaches

    Author : Davide Di Francesco; Joseph Samec; Orlando Rojas; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Lignin; biomass; catalytic fractionation; dearomatization; heterogeneous catalysis; organisk kemi; Organic Chemistry;

    Abstract : This work aims to explore different approaches for the valorization of lignocellulosic biomass. In this regard, two different strategies are presented: the catalytic upgrading of lignocellulose derivatives from industrial streams, such as pyrolytic oil and kraft lignin, and the direct catalytic fractionation of woody biomass.

  5. 3. Multicomponent Catalytic Reactions : Theoretical and Experimental Studies

    Author : Martin Pauze; Enrique Gomez Bengoa; Belen Martin-Matute; Vincent Gandon; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; C-H Activation; Quaternary Quinolinium; Organocatalyst; Transition Metal Catalyst; Umpolung Strategy; Multi-step Reactions; Mechanistic Investigation; Density Functional Theory; organisk kemi; Organic Chemistry;

    Abstract : In this thesis, Density Functional Theory (DFT) methods have been applied to study the mechanisms of three different multicomponent organic reactions. Also, a new synthetic procedure for the preparation of quinolinium salts is presented, and its mechanism also studied by DFT calculations. READ MORE

  6. 4. Catalytic Asymmetric Ketone and Alkene Reductions Using Transition Metal Complexes

    Author : Klas Källström; Pher Andersson; Per Arvidsson; Jonathan Williams; Uppsala universitet; []
    Keywords : Organic chemistry; Catalytic; Asymmetric; Reductions; Ketones; Alkenes; Transition metal; Complexes; Organisk kemi;

    Abstract : This thesis contains seven papers dealing with iridium and ruthenium based catalytic asymmetric reductions, either of ketones into chiral alcohols, or olefins into chiral alkanes. The first part of the thesis describes how we have designed and evaluated new bicyclic ligands containing either N,S or N,N chelating atoms. READ MORE

  7. 5. A Study of Biomass Combustion Problems and the Selective Catalytic Oxidation of Ammonia

    Author : Göran Olofsson; Kemiska institutionen; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical technology and engineering; Kemiteknik och kemisk teknologi; Energy research; Reaction mechanism; Ammonia degradation; Pt CuO Al2O3 Catalysts; SCO; Selective Catalytic Oxidation; Catalytic hot gas cleaning; Bed agglomeration; NOx emissions; Fluidised bed; Biomass combustion; Biogas; Energiforskning;

    Abstract : Increasing awareness of the need of reducing CO2, NOx and SOx emissions from combustion systems has led to a strong interest in biomass as a fuel source. Using it in combination with fluidised bed combustion technology can lead to a lowering of NOx emissions to the atmosphere. READ MORE
