ABSTRACT:
A paraffin isomerization process is described and claimed. The process involves contacting the paraffins with an isomerization catalyst at isomerization conditions. Additionally, the process requires the injection of a nitrogen containing compound such as an amine, e.g., t-butylamine, and raising the operating temperature by about 20.degree. C. to about 150.degree. C. The effect of these modifications is to provide improved selectivity and sulfur resistance to the catalyst.
