ABSTRACT:

In this quarter the authors studied the isomerization and hydrocracking of paraffins in the presence of aromatics and naphthenes. It was found that one could alkylate aromatics and naphthenes with paraffins over a Pt/ZrO(2)/SO (4) catalyst at 160 C and 350 psig of H(2) (380-420 psig during the reaction). Surprisingly, 75 wt% of cyclohexane was alkylated by alkyl groups derived from n-heptane and 33 wt% of toluene was alkylated under the same conditions. Addition of aromatics and hydride transfer agents to the paraffinic feed affects product distributions and conversions, probably by modifying the acidity of the Pt/ZrO(sub 2)/SO(sub 4), catalyst. It appears that one may be able to control the product distribution from conversion of long-chain paraffins by use of suitable agents. A letter describing these results has been accepted for rapid publication by the journal, Applied Catalysis. A copy is attached as an appendix.
