  1. 1. Cobalt supported on mesoporous silicas for the Fischer-Tropsch synthesis

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

    Författare :Esther Donado Sainz de la Maza; [2012]
    Nyckelord :Fischer-Tropsch; cobalt; titania; SBA-15; water;

    Sammanfattning : This thesis deals with the study of several catalysts for the Fischer-Tropsch synthesis in the Biomass-To-Liquid process. In this work two groups of catalysts were tested. On the one hand, two series of catalysts with cobalt loadings of 6 and 12 wt% over SiO2 and some of them containing 5wt% of TiO2 were tested. LÄS MER

  3. 2. SBA-15; an investigation into the synthesis solution's effect on formation dynamics and material properties

    Kandidat-uppsats, Lunds universitet/Kemiska institutionen

    Författare :Caroline Anderberg Haglund; [2012]
    Nyckelord :Fysikalisk kemi; Chemistry;

    Sammanfattning : The aim of this thesis project was to study the reaction solution’s effect on the formation dynamics and material properties of the mesoporous silica SBA-15. The common synthesis procedure of SBA-15 was applied at 60°C, with 2.5 wt% Pluronic P104 dissolved in 1.6 M hydrochlorid acid. LÄS MER

  4. 3. SBA-15 SiOx as Mesoreactor for Copper Nanoparticles

    Master-uppsats, Nanostrukturerade material; Institutionen för fysik, kemi och biologi

    Författare :Hao-Tso Tsai; [2009]
    Nyckelord :Copper nanoparticles; mesoporous silica; mesoreactor; SBA-15;

    Sammanfattning : The work presented in this thesis has been focus on developing the idea of mesoreactor based on mesoporous silica SBA-15. SBA-15 is a mesoporous material with highly ordered pore structure and tailorable pore sizes with narrow sizes distribution. LÄS MER
