1. The chemical nature of CO2 adsorption in zeolite A
Sammanfattning : The climate changes are accelerated by increasing levels of carbon dioxide in the atmosphere connected to the fossil-fuel-based energy system. Substantial reforms of the system are needed immediately and could include the implementation of carbon capture and storage (CCS) technologies. LÄS MER
2. 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
3. Operational strategies to control the gas composition in dual fluidized bed biomass gasifiers
Sammanfattning : Steam gasification of biomass can increase the share of renewable energy and material resources in the energy sector, transportation and different industries. Prior its application, the raw gas produced in biomass gasifiers needs to be cleaned from impurities. LÄS MER
4. Strategies for controlling solid biomass conversion in dual fluidized bed gasifiers
Sammanfattning : In the chemical industry, Synthesis Gas (syngas) has been traditionally produced by steam reforming of natural gas and naphtha. Steam gasification of biomass offers an alternative route for the production of syngas from renewable sources. LÄS MER
5. An in-situ ATR-FTIR Study of the Adsorption Properties of MFI Type Zeolites for Upgrading of Biofuels
Sammanfattning : With the depleting reservoirs of fossil fuels, increasing environmental concerns for flue-gas emissions from fossil-fuel combustion and growing world population, the need for the development of new sustainable fuels is higher than ever. However, to be able to compete with today’s mature technologies for production of fuels from fossil sources, new efficient processing alternatives for upgrading of biofuels must be developed. LÄS MER
