Troubleshoot silicon contamination on catalysts
What are the sources, impacts and possible solutions to controlling this problem in your hydrotreater?
Using new upstream technologies and diversified feedstocks from different sources
has increased the level of silicon contamination that has a
significant impact on hydrotreating catalyst activity. Silicon
deposition on hydrotreater catalyst surfaces significantly
reduces its desulfurization activity. In addition, silicon
deposition renders the catalyst non-regenerable. During
regeneration, the silicon would be irreversibly adsorbed onto
the entire catalyst surface, thereby further deactivating
