1. Heterogeneously Catalyzed Valorization of Monoterpenes to High Value-Added Chemicals
Sammanfattning : A potential industrial process is profitable only if it is successfully implemented by the continuously developing chemical industry. Throughout last decades heterogeneous catalysis has opened doors to the creation of various know-how products which previously were considered unfeasible. LÄS MER
2. Removal of Micropollutants from Wastewater : evaluation of effect of upgrading ozonation to electro-peroxone
Sammanfattning : The United Nations (UN) has adopted 17 “Sustainable Development Goals” (SDGs) to achieve a clean, better and sustainable future. SDG 6 is to ensure that everyone has access to clean water and sanitation by 2030. LÄS MER
3. Facilitating electron transfer in bioelectrocatalytic systems
Sammanfattning : Bioelectrocatalytic systems are based on biological entities, such as enzymes, whole cells, parts of cells or tissues, which catalyse electrochemical processes that involve the interaction between chemical change and electrical energy. In all cases, biocatalysis is implemented by enzymes, isolated or residing inside cells or part of cells. LÄS MER
4. Catalytic Steam Pyrolysis of Biomass for Production of Liquid Feedstock
Sammanfattning : The current societal needs for fuels and chemical commodities strongly depend on fossil resources. This dependence can lead to economic instabilities, political problems and insecurity of supplies. LÄS MER
5. Enhanced Catalytic Pyrolysis of Biomass for High-Quality Biofuel Production
Sammanfattning : The rapid increase in energy demand, the extensive use of fossil fuels, and the urgent need to reduce carbon dioxide emissions have raised concerns in the transportation sector, since transportation has been primarily dependent on fossil fuels. Biofuel from biomass can make significant contributions to overcome the expected depletion of fossil fuels and reduce carbon emissions. LÄS MER
