1. High flux zeolite membranes for efficient production of biofuels
Sammanfattning : The greenhouse effect and the limited fossil oil resources have increased the demand for renewable fuels. Zeolite membranes have potential applications in numerous separation processes, and could be useful in the development of efficient processes for renewable fuel production. LÄS MER
2. Factors affecting MFI membrane quality
Sammanfattning : Zeolites are crystalline aluminosilicates with molecular sieving properties and are widely used in industrial applications such as catalysis, sorption and ion-exchange. Zeolite membranes are highly interesting due to their capability to continuously separate molecules under severe conditions. LÄS MER
3. Separation of Biomass Components by Membrane Filtration - Process Development for Hemicellulose Recovery
Sammanfattning : One of the major challenges facing the world today is the reduction of our dependency on fossil resources as their exploitation has severe negative effects on the environment. One way of realizing this is to utilise the components of lignocellulosic biomass to a greater extent as feedstock for various industrial products. LÄS MER
4. Zeolite Membrane Separation at Low Temperature
Sammanfattning : The energy consumption of separation processes accounts for a large part of the total energy consumption in chemical industry. Membrane separation processes require much less energy than the currently used thermally driven separation processes and could therefore reduce energy consumption in industry considerably. LÄS MER
5. Galactoglucomannan recovery from softwood spent sulfite liquor: Challenges, process design and techno-economic evaluations
Sammanfattning : In the production of pulp and paper, water-soluble components, such as hemicellulose, monosaccharides, and lignin, are released and accumulate in the process water. The process water is usually concentrated and incinerated for heat generation and the recovery of pulping chemicals, such as in the Kraft and sulfite processes. LÄS MER
