[Solved] Why does the carbon 5-carbon 6 isomerization catalyst require activation treatment?
Thread Content
The catalyst in the isomerization section of our reforming unit needs to be activated; I’m not sure about the principle behind this
Catalysts are generally inert, so they need to be activated in order to function as catalysts
The new agent has low oxidative activity and must be reduced in order to activate its properties.
The active components of many catalysts are in an inert or passivated state at the time of manufacture (in the form of stable compounds such as oxides or salts), to ensure safety during transportation and storage. After being loaded into the catalytic reactor, the catalyst must be activated through appropriate methods in order to exert a catalytic effect in the subsequent reaction processes.
Many catalysts need to be treated before use; for example, hydrogenation catalysts must be pre-sulfurized before they can be put into operation.
Most catalysts also need to be treated before use; for example, hydrogenation catalysts must be pre-sulfurized before they can be put into operation.
Is pre-sulfurization meant to keep the catalyst’s activity from being too high?
Pre-sulfidation is the process of converting the catalyst from an oxidized state to a sulfided state!
Catalysts that have been in use for a long time experience a decrease in activity, an increase in pressure drop across the catalyst bed, coking of the catalyst, and unsatisfactory product quality; therefore, they need to be activated and regenerated to restore their activity.
In our case, the heterogenization catalyst is oxidized before use, and it needs to be activated by exposing it to air at high temperatures; wouldn’t that result in even greater oxidation?
Could you tell me about your specific steps? Regeneration by air flow, or burning? After passing air through, does hydrogen need to be reduced?
