Although the deactivation of heterogeneous catalysts via coking has been the subject of much investigation, there is insufficient basic knowledge to develop truly predictive models for coke deposition that would optimize the design and operation of a number of important hydrocarbon conversion processes in the oil and petrochemical industries. To overcome this drawback a generic scheme will be developed to characterise both the structure and spanial distribution of catalytic coke and it will be applied to FCC, reforming and hydrotreating catalysts. The scheme uses the quantitative solid state 13 C N MR methodology developed at Strarthclyde to determine the bulk structure of hard coke, in conjunction with the appropriate chromatographic and spectrometer techniques to detect the entrained molecular species (soft coke). These techniques with the pore size distributions elucidated by SANS. Hg porosimetry, surface area and 129 Xe NMR measurements will provide all the information needed to develop predictive models for deactivation behavior. A fundamental understanding of the important changes in coke structure that occur in stripping FCC Catalysts and govern regeneration will be obtained. For reforming and hydrotreating processes, the scheme will be used to relate coke composition with loss of activity with time on stream in order to predict catalysts lifetimes.
