The Pennsylvania State University teamed with Spectral Energies, LLC to develop appropriate spatiotemporal imaging capabilities in single body zeolites to describe beneficial and parasitic catalytic cracking pathways. Synthetic methods to produce mordenite framework inverted MFI crystals with dimensions as large as 150 micron x 50 micron x 20 micron were utilized to produce catalysts that could be imaged by a suite of optical techniques, including coherent anti-Stokes Raman spectroscopy CARS, resonance Raman spectroscopy and two-photon fluorescence. The crystals with varying SiAl ratio were characterized by temperature programmed desorption of base probe molecules and the Al distribution in the crystals was mapped by electron probe microanalysis EMPA. We demonstrated the ability to follow in a spatiotemporal fashion, the decomposition of the structure-directing agent used to template the zeolite during growth, and the conversion of surrogate fuels in MFI and the ability to selectively identify individual species through their vibrationalscattering fingerprints.
