Z-700A is used in refineries and petrochemical complexes where the isomerization of pentane and hexane is required to produce a high-octane gasoline blending component.  Performance tests of Z-700A have demonstrated its resilience to sulphur poisoning and successful recovery from such incidents. Z-700A can be used in all reactor types utilised for this process: classical fixed bed reactors, radial flow reactors, etc.
