Process and System for the Addition of Promoter Metal In Situ in a Catalytic Reforming Unit

Abstract

One exemplary embodiment can be a process for facilitating adding a promoter metal to at least one catalyst particle in situ in a catalytic naphtha reforming unit. The process can include introducing a compound comprising the promoter metal to the catalyst naphtha reforming unit and adding an effective amount of the promoter metal from the compound comprising the promoter metal to the catalyst particle under conditions to effect such addition and improve a conversion of a hydrocarbon feed.

Description

FIELD OF THE INVENTION[0001]The field of this invention generally relates to a process for conversion of hydrocarbons in a catalytic reforming unit.DESCRIPTION OF THE RELATED ART[0002]Numerous hydrocarbon conversion processes can be used to alter the structure or properties of hydrocarbon streams. Generally, such processes include: isomerization from straight chain paraffinic or olefinic hydrocarbons to more highly branched hydrocarbons, dehydrogenation for producing olefinic or aromatic compounds, dehydrocyclization to produce aromatics and motor fuels, alkylation to produce commodity chemicals and motor fuels, transalkylation, and others.[0003]Typically such processes use catalysts to promote hydrocarbon conversion reactions. As the catalysts deactivate, it is generally desirable to regenerate them and / or add new catalyst to improve yields and profitability.[0004]Various catalysts and processes have been developed to convert hydrocarbons. Often, such processes require periodic reg...

Benefits of technology

[0005]One exemplary embodiment can be a process for adding a promoter metal catalyst component in situ in a catalytic naphtha reforming unit. The process can include introducing a compound comprising the promoter metal catalyst component to the catalytic reforming process under conditions to effect deposition of the promoter metal onto the catalyst particle and improve a conversion of a hydrocarbon feed. Selectivity of the catalyst particle may be improved, activity of the catalyst particle may be improved, deactivation of the catalyst particle may be reduced, undesired coking behavior of the catalyst particle may be reduced, or any combination of the above.

Problems solved by technology

Generally, one drawback of replacing an existing catalyst with a new catalyst is the cost of replacing a large volume of catalyst, especially if the existing catalyst is not at its useful end of life.
