| Abstract: | Hydrotreating catalyst and catalytic cracking catalyst with carbon deposition were characterized by transmission electron microscopy.The analytical results of scanning transmission electron microscopy/energy dispersive X-ray spectroscopy showed that the particles in the oxidized hydrotreating catalyst were collections of active metal components.The element mapping of carbon and aluminum in calalytic cracking catalyst with carbon deposition was obtained by energy filter transmission electron microscopy. |
