  1. 6. Spatiotemporal reconstructions of black carbon, organic matter and heavy metals in coastal records of south-west Sweden

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Marcus Rudolf; [2016]
    Nyckelord :organic matter; spheroidal carbonaceous particles; black carbon; geology; physical geography; Ecosystem analysis; heavy metals; coastal sediments; Sweden; Earth and Environmental Sciences;

    Sammanfattning : This study presents reconstructions of black carbon (BC), including spheroidal and amorphous carbonaceous particles (SCP and ACP), organic matter (OM; total organic carbon, TOC; total nitrogen, TN; total sulfur, TS), and heavy metals (Fe, Zn, Pb, Cu, As and Hg) in coastal sediments off the south-west coast of Sweden. Sediment records from eight stations along a north-south transect off the south-west of Sweden were retrieved. LÄS MER

  3. 7. Methods of high-dimensional statistical analysis for the prediction and monitoring of engine oil quality

    Master-uppsats, KTH/Matematisk statistik

    Författare :Fredrik Berntsson; [2016]
    Nyckelord :;

    Sammanfattning : Engine oils fill important functions in the operation of modern internal combustion engines. Many essential functions are provided by compounds that are either sacrificial or susceptible to degradation. The engine oil will eventually fail to provide these functions with possibly unrepairable damages as a result. LÄS MER

  4. 8. Metaloxid katalysatorer för oxidering av kolmonoxid och förbränning av sot

    Master-uppsats, KTH/Skolan för kemivetenskap (CHE)

    Författare :Miguel GÓMEZ AGUILERA; [2015]
    Nyckelord :CO oxidation; cobalt oxide; ceria; soot combustion; diesel.;

    Sammanfattning : The aim of this work was to manufacture and test non noble metal catalysts for CO oxidation and soot combustion. The feeding gases consist in the products of the combustion diesel in a Reformtech heater. These gases contain CO, CO2, H2O as well as small amounts of NOx and hydrocarbons. LÄS MER

  5. 9. Chemical analysis for mapping of soot reactivity

    Uppsats för yrkesexamina på grundnivå, KTH/Skolan för kemivetenskap (CHE)

    Författare :Henrik Pettersson; [2013]
    Nyckelord :diesel soot; reactivity; oxidation; rail pressure; EGR; TGA; SEM; EDS;

    Sammanfattning : In order to increase the efficiency of diesel particulate filter regeneration more knowledge about diesel soot and its reactivity is required. This thesis compares soot created during accelerated filter loading by lowered rail pressure, with soot from normal filter loading. LÄS MER
