CKS ISOM Naphtha Isomerization
"Convert Your Paraffinic Naphthas into Full Octane Participants"

The M W Kellogg Technology Company 03 December 1997
This year, The M. W. Kellogg Technology Company formed an alliance with CEPSA and Sud-Chemie to make available for license a new CJC, isomerization process. CKS ISOM processes light naphtha streams to provide an octane upgrade for gasoline blending. Or, as the subtitle of my talk states,CKS ISOM will "convertyour paraffinic naphthas into full octane participants."

The CKS ISOM Process
Process Features .Alliance - The "CKS"
As an introduction,we will briefly review C,/C, isomerization and the driving forces for its use today. This will leadto how an isomerizationunit fits into the refinery scheme. Given these basics, we will presentto you the CKS ISOM process and our experience. We will discuss the particular features which can only be provided by our CKS ISOM technology. Finally, the strengths of the supporting alliance for CKS ISOM are described.

Product mix characterizedby thermodynamic equilibrium which is function of temperature
The isomerizationreaction rearranges short straight chain c& hydrocarbons which are fully saturated. This rearrangement takes place in the presence of hydrogen and is carried out over a catalyst. The catalyst speeds the reaction mixturetowards the thermodynamic equilibrium. This equilibrium is a function of temperature and controls the product composition.
For C5paraffins, there are two principal isomers, normal pentane and isopentane. There are five combinations of c6 paraffins. Two of these are dimethylbutanes, two are methylpentanes, and the last is normal hexane. The value of these components to a refiner is inherent in their chemical structure. Higher octane is associated with the more branched compounds. The dimethylbutanes or isopentane, being the most branched forms, have the highest octane value. The lowest octane value is in the straight carbon chain found in normal hexane.
Saturated C, cyclical compounds will also undergo rearrangement in the isomerization process. Athermodynamic equilibrium is established between cyclohexane (CH) and methylcyclopentane(MCP).
