  6. 4. Ash chemistry and fuel design focusing on combustion of phosphorus-rich biomass

    Author : Nils Skoglund; Dan Boström; Rainer Backman; Franz Winter; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; phosphorus; biomass; combustion; ash chemistry; fuel design; ash transformation; phosphorus-rich; ash-forming elements; fuel fingerprint; ash transformation reactions; Lewis base; Lewis acid; oorganisk kemi; Inorganic Chemistry;

    Abstract : Biomass is increasingly used as a feedstock in global energy production. This may present operational challenges in energy conversion processes which are related to the inorganic content of these biomasses. As a larger variety of biomass is used the need for a basic understanding of ash transformation reactions becomes increasingly important. READ MORE

  7. 5. Lewis Acid Mediated [2,3]-Sigmatropic Rearrangement of Allylic Ammonium Ylides

    Author : Jan Blid; KTH; []
    Keywords : Sigmatropic rearrangement; Lewis acid; Ammonium ylide; NMR spectroscopy; Density functional calculations;

    Abstract : This thesis describes a Lewis acid mediated[2,3]-sigmatropic rearrangement of various allylic ammoniumylides. Several Lewis acids are investigated and BBr3 and BF3are established to be the Lewis acids providing the highestconversion of the starting allylic amines. READ MORE
