This paper describes the Catalytic Reforming Process for upgrading naphtha feedstocks to high octanes using a regenerable platinum catalyst. Particular reference is made to the Powerforming Process developed by Esso Research and Engineering Company and in use by Imperial Oil Limited.

The various types of fixed bed units are described and a simplified flow plan of a typical Powerforming Unit is illustrated. The general operation of the unit is discussed as well as the primary reactions involved in catalytic reforming. Operating conditions are listed and some product yields and quality are shown in a table for various feedstocks.

Regeneration is required to reactivate the catalyst by burning off carbon and sulphur compounds laid down during the oil cycle. A general description of how this is carried out on a unit containing a swing reactor is outlined.
