Powerforming process

Until the early 1970 s, two methods were widely used, namely semi-regenerative and cyclical regenerative processes. The UOP semi-regenerative process (UOP platform process) is particularly common the Exxon Powerforming process and the Atlantic Richfield/Engelhard Magnafomang process operate in a similar way. 

Several significant reforming processes are ia use (37,38). These iaclude Powerforming (Exxon), Ultraforming (Standard Oil Co.), Rheniforruing... 

Powerforming is basically a conversion process in which catalytically promoted chemical reactions convert low octane feed components into high octane products. The key to a good reforming process is a highly selective dual-function catalyst. The dual nature of this catalyst relates to the two separate catalyst functions atomically dispersed platinum to provide... 

Powerforming is a version of the platinum reforming process. Basically there are two types of unit semi-regenerative and cyclic. The choice of unit and the exact process conditions used will depend to a large extent on the particular application. However, certain generalizations regarding each of the two types can be made. 

There are several versions of the two-step process. One involves the use of 5A molecular sieves in conjunction with Powerforming. In this combination process, the 5A sieves may be used to remove n-paraffms from the feed to improve feed quality. Alternatively, the Powerformate may be sieved to remove the low octane n-paraffm components. Extraction of aromatics from Powerformate is another interesting two-step process. 

Ethylbenzene is separated from mixed xylenes by fractionation using 360 trays and a high reflux ratio. Ethylbenzene is separated from the closest isomer paraxylene whose normal boiling point is only 3.90°F higher. The average relative volatility between ethylbenzene and paraxylene in the fractionation is about 1.06. The fractionator feed is entirely Cg aromatics which are prepared by the extraction of powerformate by the sulfolane process and by fractionation of the aromatic extract.
