Spectroscopic investigation of acidity, diffusion and activity of zeolites for polypropylene cracking

Analysis of acidic and catalytic properties supported by studies of diffusion of neopentane, both experimental and theoretical, is provided. The advanced in situ and operando FT-IR spectroscopy technique supported by chromatographic and mass spectrometry methods were employed to evaluate the acidity, diffusivity and catalytic activity of studied catalysts. Polypropylene cracking as a model reaction.
