  1. 1. NOx Adsorption and Transport in ZSM-5 Films

    Författare :Indra Perdana; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wicke-Kallenbach cell; mathematical modelling; NOx adsorption and transport; adsorbed species; ZSM-5 films; permeation;

    Sammanfattning : The present work dealt with a fundamental study of NOx adsorption-desorption and transport in ZSM-5 as films supported on cordierite monolith and as a part of composite membranes. The adsorption-desorption study was focused on developing a mechanistic understanding of NOx adsorption in ZSM-5 films including the effects of counter-ions, Si/Al ratios and film thicknesses on the adsorption.

    Sammanfattning : This work dealt with studies of NOx adsorption in films of ZSM-5. The study was interesting due to its significant contribution to develop a detailed understanding of NOx transport and adsorption in ZSM-5 which is of interest for catalyst or membrane applications. LÄS MER

  4. 3. Thin films of molecular sieves : synthesis and applications

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

    Sammanfattning : The seed film method for synthesis of ultra thin and thin molecular sieve films was developed. The versatility of the method was demonstrated by successful preparation of films of a number of molecular sieves (silicate-1, ZSM-5, NA) on various supports (silicon, alumina, gold, etc.). LÄS MER
