2. Integrated membrane reactor for the production of butyl butyrate starting from biomass
University essay from KTH/Fiber- och polymerteknologiAbstract : Efterfrågan på energi ökar snabbt, och denna trend förväntas bestå. Det råder dock ingen tvekan om att världen för närvarande befinner sig i en energikris, som är en katastrof både ekonomiskt och miljömässigt. Följaktligen är sökandet efter alternativa energikällor för att ersätta fossila bränslen absolut nödvändigt. READ MORE

3. Amino Acid Analysis : Establishment of a GC-FID method for Amino Acid Analysis in Legumes
University essay from Linnéuniversitetet/Institutionen för kemi och biomedicin (KOB)Abstract : Demands for plant-based diets sufficient in all required amino acids are increasing due to health and environmental advantages. As legumes offer a complementing source of quality protein to the already heavily consumed cereals, methods for determining amino acid compositions in legumes are needed. READ MORE

4. Analysis of polyfunctional thiols in beer : Developing a novel method of extraction and analysis using GC-FID
University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)Abstract : In this project, attempts were made to identify and quantify two polyfunctional thiols – 4-mercapto-4-methyl-pentanone and 3-mercaptohexyl acetate – and three monoterpene alcohols – linalool, geraniol, and β-citronellol – in beer samples. In order to avoid the use of hazardous compounds such as dichloromethane and hydroxymercuriobenzoate, common in traditional methods, two novel techniques were tested: a pure liquid-liquid extraction of the beer samples with cyclohexane, and a liquid-liquid extraction with cyclohexane followed by solid phase extraction on silver ion columns.

5. Development of a GC Method for the Quantification of Short Chain Carboxylic Acids in Aqueous Solution
University essay from Linköpings universitet/Institutionen för fysik, kemi och biologiAbstract : Petroleum powered vehicles emit volatile organic compounds (VOCs) through combustion that contributes to the pollution of the environment. A technique in the 1970s was developed to decrease these emissions, especially for nitrogen oxides (NOx) and sulphuric oxides (SOx) which is called exhaust gas recirculation (EGR). READ MORE
