Contributor Moulijn, J.A. (promotor) Faculty Applied Sciences Date 2007-09-10 Abstract Branched hydrocarbons are preferred to linear hydrocarbons as ingredients in petrol, as they enhance the fuel octane number. By catalytic isomerisation linear hydrocarbons are converted into branched hydrocarbons, then it becomes necessary to separate the mixture. A variety of zeolites may be used for this purpose, either on thermodynamics or kinetics basis. Therefore, adsorption and diffusion data are essential to the development of sorption based separation methods, but also they provide key information regarding the catalytic isomerisation over zeolites. However, the experimental assessment of multi-component adsorption data is not straightforward and is highly time-consuming. To approach this problem a new experimental set-up was designed that combines a manometric apparatus with Near-InfraRed (NIR) spectrometer. NIR spectroscopy is a non-intrusive technique that allows to monitor the composition of the gas phase (including isomers) and its changes in a time resolved manner.
