3. 17. An in-situ ATR-FTIR Study of the Adsorption Properties of MFI Type Zeolites for Upgrading of Biofuels

   Författare :Amirfarrokh Farzaneh; Willis Forsling; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical Technology; Kemisk teknologi;

   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.

4. 18. Structured MFI film catalysts and adsorbents

   Författare :Olov Öhrman; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical Technology; Kemisk teknologi;

   Sammanfattning : A method originally developed at the division of Chemical Technology, Luleå University of Technology was tailored for the preparation of well-defined ZSM-5 films and zoned MFI films on supports suitable for catalysis and adsorption applications. Films were grown on monoliths, ceramic foams, alumina beads, soda glass beads and quartz glass. LÄS MER

5. 19. Study of H2/CO/CO2 adsorption on MFI zeolites for CO2 selective WGS membrane reactor concept

   Författare :Sang Wirawan; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; FTIR spectra; CO2 selective; adsorption; MFI zeolites; Langmuir model; WGS membrane reactor; TPD;

   Sammanfattning : The single-component adsorption behavior of CO, CO2 and multi-component adsorption of H2/CO2, CO/CO2, and H2/CO/CO2 on silicalite-1 and cation exchanged MZSM-5 zeolites (M = H, Na, and Ba) were investigated by a step change response method. Temperature programmed desorption (TPD) and in-situ fourier transform infrared (FTIR) spectroscopy were also performed to study the type of adsorbed species and their thermal stabilities. LÄS MER

7. 20. Modified molecular sieve macrostructures

   Författare :Valeri Naydenov; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical Technology; Kemisk teknologi;

   Sammanfattning : The preparation of molecular sieve based catalysts in appropriate macroforms suitable for practical utilization is of great technological importance. This thesis is dedicated to the preparation of metal containing molecular sieve macrostructures (modified macrostructures). LÄS MER
