  • Disproportionating C.sub.2 -C.sub.6 paraffins over zeolites
    Patent number: 3953537
    Abstract: A process for disproportionating a paraffinic hydrocarbon containing 2 to 6 carbon atoms to produce paraffinic hydrocarbons containing one more and one less carbon fragment per molecule is disclosed. In the process the paraffinic hydrocarbon is contacted at about 400.degree. to 1000.degree.F. with an acidic, crystalline aluminosilicate catalyst having a pore size of about 8 to 15 A, silica to alumina mole ratio greater than 2 to 1 and at least about 0.4 equivalent per gram atom of aluminum of hydrogen or metal ion.
