ANS:C - Platforming

The non-regenerative fixed bed catalytic reforming process among the options listed is Hydroforming. Here’s a brief explanation of each term for clarity:

1. Hydroforming: Hydroforming is a non-regenerative fixed bed catalytic reforming process where the reforming reactions occur under hydrogen pressure. It involves the use of a fixed catalyst bed that is not regenerated during operation.
2. Thermofer Catalytic Reforming: This term does not typically describe a widely recognized catalytic reforming process. It may refer to a specific proprietary or less common process.
3. Platforming: Platforming is a well-known catalytic reforming process used in petroleum refining. It involves a continuous regeneration of the catalyst to maintain its activity.
4. Hyperforming: Hyperforming is not a widely recognized term in the context of catalytic reforming processes. It may refer to a specific proprietary process or a less common method.
