Peculiar Diffusion Mechanisms within Micropores of Zeolite Catalysts
Diffusivity MFI zeolit Adsorption controlled diffusion Multi-component system
2009/7/23
Diffusion mechanisms of hydrocarbons within zeolites, especially MFI-type zeolite, were investigated by discriminating intracrystalline diffusivity from effective diffusivity. Intracrystalline diffus...
