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 active sites.
