1. Recovery of Dialcohol Cellulose using Micro- and Ultrafiltration Processes
Master-uppsats, Lunds universitet/Kemiteknik (CI)Sammanfattning : The waste management and production of plastic play a concerning part in global warming and continues to have a negative effect on the environment. A promising strategy to address this challenge is to develop new sustainable materials, to replace current fossil-based plastics. LÄS MER
2. Lignin modification for higher reactivity towards epoxides
Master-uppsats, KTH/Fiber- och polymerteknologiSammanfattning : Fem metoder har använts för att modifiera barrvedslignin med syftet att öka reaktiviteten av ligninet mot epoxidgrupper. Ligninprover analyserades med NMR och FTIR medan reaktivitet var mätt genom reometri. Metoder som ökade mängden karboxylsyragrupper på ligninet minskade ligninets reaktivitet. LÄS MER
3. Alkaline wet oxidation of biorefinery lignin from wheat straw
Master-uppsats, Lunds universitet/Kemiteknik (CI)Sammanfattning : Climate change and depletion of fossil resources have generated a need for energy production based on renewable resources such as lignocellulosic biomass. Agricultural residues, like wheat straw, is lignocellulosic biomass that could contribute to the energy supply if it was used for biogas production. LÄS MER
4. Oxidation of veratryl alcohol with lignin peroxidase and nanoscale photosystems
Kandidat-uppsats, Uppsala universitet/Institutionen för kemi - BMCSammanfattning : .... LÄS MER
5. Evaluation of Esterification as a Valorization Route for Oxidized Lignin
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Industriell miljö- och processteknikSammanfattning : RISE Bioeconomy is working with the biorefinery concept. That is, for the company, to utilize all wood derivatives in effective processes, resulting in unique products. RISE Bioeconomy is investigating the possibilities of producing holocellulose through an oxidative delignification process of wood, using peracetic acid (PAA). LÄS MER
