1. Katalysatorval och beaktanden vid flerstegsomvandling av glukos till glycerol
Master-uppsats, Lunds universitet/Kemiteknik (CI)Sammanfattning : Through hydrogenation of glucose to sorbitol followed by hydrogenolysis of sorbitol to glycerol a pathway to produce bio propane from lignocellulosic material has been confirmed. A wide range of catalyst was tested, in an autoclave batch reactor, to scout the activity of catalysts already proven active, according to previous literature, as well as catalysts not mentioned in literature for the specific reaction.

2. Hydrogen Assisted Lignin Depolymerization with Pulp Mill Catalysts
Master-uppsats, Lunds universitet/Kemiteknik (CI)Sammanfattning : As part of the development of a process for production of a lignin-rich oil that can serve as a renewable feedstock to existing petroleum refineries, hydrogen assisted depolymerization of lignin in filtered black liquor has been investigated. This process offers the possibility to reduce fossil emissions from transportation by utilization of the largest renewable carbon resource in Sweden, namely the forest. LÄS MER
3. Noble metal catalysts for the hydrocracking of FT waxes
Master-uppsats, KTH/Skolan för kemivetenskap (CHE)Sammanfattning : Bifunctional catalysts consisting of palladium or platinum and supported on amorphous silica-alumina were prepared and tested in the hydrocracking of n-hexadecane, which is considered to be representative of n-paraffins in hydrocracker feeds. In addition to the evaluation of the physicochemical properties, a comprehensive study on catalyst activity and selectivity has been conducted, in the full range of conversions. LÄS MER
4. Noble Metal Catalysts for the Hydrocracking of Fischer-Tropsch waxes
Master-uppsats, KTH/Skolan för kemivetenskap (CHE)Sammanfattning : Fischer-Tropsch synthesis enables the production of high quality diesel fuel from biomass derived synthesis gas. In order to increase the overall diesel yield, it is necessary to perform a subsequent hydrocracking of the long-chain linear paraffins. LÄS MER
5. Läkemedelsutveckling med hjälp av fragmentscreening
Kandidat-uppsats, Institutionen för naturvetenskap, NVSammanfattning : Trombin är ett trypsinliknande serinproteas som har stor del i kroppens reglering av blodets fluiditet och koagulation genom att det klyver faktorer som slutligen leder till att blodet kan koagulera och fibrin bildas. Syftet med det här projektet har varit att syntetisera fragment som designats med datorgrafiska metoder på Astra Zeneca och sedan analysera fragmenten med affinitetskromatografi med trypsin immobiliserad på kiselgelspartiklar.
