Commercialization of Catalyst TCDTO-1 for Hydrogen-free Refining of Aromatics

The catalyst TCDTO-1 for hydrogen-free refining of reformate jointly developed by CNOOC’s Tianjin Chemical Research and Design Institute and the Huizhou refinery has been successfully applied in the production process. It is said that this catalyst is the first petrochemical catalyst which is independently developed by CNOOC. This catalyst has been applied in the Huizhou refinery since November 2011, and its service life is expected to reach around 300 days, which are two times the service life of similar catalysts. Furthermore, the catalyst TCDTO-1 has good regeneration stability, because it can be stably regenerated for 2—3 times, and the reduction in the service life of regenerated catalyst would be less than 10%, and the overall life of catalyst can reach more than 2 years. Judging from either the once-pass lifetime of catalyst or the service life of regenerated catalyst, this novel catalyst for reformate refining and olefins removal in absence of hydrogen has assumed an international leading position.
