The deactivation of 4A zeolite molecular sieves under severe hydrothermal conditions is studied. Accelerated deactivation runs are performed on Uetikon and TOSOH 4A zeolite pellets, and the results are interpreted considering their equilibrium and kinetic data. A mathematical mo…

Several members of the ABC-6 zeolite family, namely offretite, zeolite T, ZSM-34 and zeolite L, were synthesised with a view to studying the effect of synthetic parameters on the resulting crystal properties. A range of procedures for producing offretite and ZSM-34 were tested, …

This thesis focuses on developing an alternative system for membrane electrode assembly (MEA) formation to use with a direct methanol fuel cell (DMFC). The approach involves incorporating inorganic fillers with an industry standard Nafion polymer as part of a methanol resistant …

There are some abundant long chain n-alkanes in refinery stream fuels which have a lower octane number and a higher pour point. It would be thus desirable to convert these normal paraffins to their branched isomers (which have higher octane number). Novel classes of cation incor…
