Abstract
A process for reverse isomerization of a light naphtha feedstock containing branched C-Cparaffins. The process includes feeding a mixed feed stream including the light naphtha feedstock to a separation unit to generate an iso-paraffin stream and one or more normal paraffin streams. The process further includes mixing hydrogen gas and a hydrocarbon feed stream containing the iso-paraffin stream to form a hydrogen-enriched liquid feed stream which is provided to a reverse isomerization reactor. The hydrogen-enriched liquid feed stream is contacted with a solid reverse isomerization catalyst for reverse hydroisomerization in a substantially two-phase liquid-solid reverse isomerization fixed-bed reaction zone convert iso-paraffins to normal paraffins. The isomerization effluent stream is provided to a stabilization column to generate a stabilized isomerate stream which is combined with the light naphtha feedstock to generate the mixed feed stream. An associated system for performing the process is also provided.
