    • A process for the continuous isomerization of an alkane to produce an isomerized product through contacting the alkane with a simulated moving bed acting as a catalyst for isomerization and an adsorbent for the alkanes has been developed. The alkane may be n-butane and the isomerized product 2-methylpropane, the alkane may be n-pentane and the isomerized product 2-methylbutane or 2,2-dimethylpropane, the alkane may have from 6 up to about 8 carbon atoms with no more than one methyl branch and the isomerized product having the same number of carbon atoms and at least two methyl branches, or the reactant may be a mixture of the foregoing alkanes with the corresponding isomerized products being formed. In a zone of the simulated moving bed, the alkanes are catalytically isomerized to form the isomerized products. The unreacted alkanes are adsorbed, and the isomerized products are collected. In a subsequent zone of the simulated moving bed, the unreacted alkanes are desorbed using a desorbent and may be catalytically isomerized to form additional isomerized products which are also separated and collected. The catalyst used in the simulated moving bed may be platinum on tungstated zirconia, and the adsorbent used in the simulated moving bed may be EU-1, ZSM-12, SAPO-5, Y-82, faujasite, erionite, zeolite beta exchanged with sodium, lithium, potassium, barium, calcium, strontium or combinations thereof, zeolite X exchanged with calcium and strontium, mordenite exchanged with sodium, lithium, potassium, barium, calcium, strontium, or combinations thereof.

    • A process for disproportionating paraffinic hydrocarbons containing three to seven, four to five, carbon atoms in a hydrogen atmosphere to yield products containing iso-paraffinic hydrocarbons containing one more and hydrocarbons containing one less carbon fragment per molecule is disclosed. In the process, the paraffinic hydrocarbon is contacted in a hydrogen atmosphere at about 700* to 900* F. with a solid, acidic catalyst comprising a minor, catalytically effective amount of a platinum-group metal and containing a hydrogen or metal exchanged crystalline aluminosilicate having pores in the 8 to 15 A range and a mole ratio of silica-to-alumina of greater than about 2 to 1 and a solid oxide support. The catalyst can contain from about 1 up to about 85 weight percent of the crystalline aluminosilicate. A preferred oxide support is silica-alumina which can further contain a minor amount of alumina such as an activated alumina of the gamma family.
