6/29

Volume Conversion in Platforming

• Aromatic: Pass essentially unchanged through the reactors

• Naphthenes:

- Almost complete conversion to aromatics, above 90 RONC

- Cyclohexanes easier to convert than cyclopentanes• Paraffins:

- Some conversion to aromatics

- Some isomerization to more highly branched isomers

- Some cracking

- Many remain in product as paraffins
