1. Thermodynamic Properties of CO2 Mixtures and Their Applications in Advanced Power Cycles with CO2 Capture Processes
Sammanfattning : The thermodynamic properties of CO2-mixtures are essential for the design and operation of CO2 Capture and Storage (CCS) systems. A better understanding of the thermodynamic properties of CO2 mixtures could provide a scientific basis to define a proper guideline of CO2 purity and impure components for the CCS processes according to technical, safety and environmental requirements.

Sammanfattning : Zeolite membranes can potentially be used for separation of many types of mixtures. The membranes can be tailored by a number of methods to suit a specific separation application. LÄS MER
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
4. An in-situ ATR-FTIR Spectroscopy Study of Adsorption in MFI Zeolites : A step towards effective upgrading of biofuels
Sammanfattning : Global warming is believed to be caused by the extensive emission of greenhouse gases, for example carbon dioxide, into the atmosphere by combustion of fossil fuels, such as coal, oil and natural gas. To reduce the emission of carbon dioxide and hence avoid global warming, alternative fuels derived from renewable resources are desired. LÄS MER
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
