Abstract:

Two types of mesoporous molecular sieves, MCM-41 and MMS, were prepared, fully characterised and tested as solid acid catalysts and catalyst support materials. Three different methods for characterising the surface acidity of these solid acids were examined and compared. These methods were 1. Fourier Transform infrared (FTIR) spectroscopy of adsorbed pyridine, 2. Pulsed ammonia adsorption using a combination of thermogravimetry and differential scanning calorimetry (TG/DSC), and 3. Temperature-programmed desorption of amines. The acidity results of these molecular sieves were compared with zeo

Abstract:

In this study, well defined ZSM-5 films were prepared on monoliths, ceramic foams, alumina beads, glass beads and crushed quartz glass by further refinement of a method originally developed at the division of Chemical Technology, Luleå University of Technology. The supports were seeded with silicalite-1 seeds and hydrothermally treated, either at 75 °C or at 150 °C in a single or several steps. By adding sodium to the solution the aluminum concentration increased in the zeolite, which is beneficial for catalytic activity. Consequently, films with different Si/Al ratios could be prepared.

This thesis is concerned with the development of sorption-effect chromatography as a rapid method for the determination of binary gas-mixture adsorption isotherms.There are many alternative non-chromatographic methods but these have inherent disadvantages the direct experimental methods require excessive equilibration times and the predictive methods require the respective pure-component isotherms and an ideal adsorbed phase. A computer simulation has shown that for an alternative chromatographic method, good results will only be obtained if both binary isotherms are close to linear. Sorption-

As a result, it was important to investigate environmentally friendly processes for the hydroxylation of aromatic compounds.
