   Sammanfattning : This thesis discusses the use of biomass as a potentially green feedstock for the chemical industry in the urgent shift away from fossil resources. I elaborate on reasons why we cannot afford to burn virgin biomass for energy production, among them a variety of ecosystem services that forests and other lands provide. LÄS MER

3. 22. Defects in Zeolite Catalysts and Membranes

   Författare :Mohammad Sadegh Nabavi; Farid Akhtar; Johanne Mouzon; Bhaskar Reddy Sudireddy; Luleå tekniska universitet; []

   Sammanfattning : ZSM-5 is one of the most well-known zeolites. It has been synthesized for many different applications, including as catalyst for catalytic reactions and as a membrane in separation processes.  The main goal of this thesis is to investigate and characterize the defects in crystal and film growth of ZSM-5 for modification purposes.

4. 23. Structured zeolite adsorbents for PSA applications

   Författare :Alessandra Mosca; Joeri Denayer; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical Technology; Kemisk teknologi;

   Sammanfattning : Zeolites are microporous crystalline aluminosilicates with unique properties, and are therefore used in adsorption processes, for membrane separation, and as catalysts. Thin zeolite films grown on honeycomb monolith supports represent a new type of material and may be used as structured catalysts and adsorbents, and improve the processes significantly. LÄS MER

5. 24. Zeolite Membranes for Production of Biofuels

   Författare :Erik Sjöberg; Joaquin Coronas; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical Technology; Kemisk teknologi;

   Sammanfattning : To deal with the increasing demand of renewable fuels, more efficient processes for the production of biofuels are needed. Zeolite membranes have the potential to improve many existing processes that could be used for production of biofuels. Methanol is a potential biofuel that may be produced from synthesis gas in an equilibrium limited reaction. LÄS MER
