Elemental analysis, powder x-ray diffraction (XRD), atomic force microscopy (AFM), solid state magic angle spinning nuclear magnetic resonance (MAS NMR), nitrogen porosimetry together with microcalorimetry experiments with ammonia have been used to characterize the surface properties of a  fluid cracking catalysts (FCC) before and after usage in a refinery and after regeneration of the spent FCC with the DEMET process.
