ABSTRACT:
A C.sub.4 -C.sub.6 feed to an isomerization zone containing substantial amounts of cyclic hydrocarbons is contacted with a high chloride, platinum alumina catalyst to simultaneously open cyclic hydrocarbon rings and isomerize paraffins to more highly branched paraffins. The process can operate at relatively low severity conditions that provide favorable equilibrium conditions for isoparaffin conversion. The ring opening is also obtained without excessive generation of light hydrocarbons. Multiple stage reaction zones may be used to operate the first stage at slightly higher severity than the second stage to maximize ring opening and obtain favorable equilibrium of iso to normal paraffins.
