摘要： The present invention is a process to upgrade light naphthas comprising branched paraffins and their use as a feedstock in a steam cracking unit, said light naphthas consisting essentially of 90 to 100% by weight of hydrocarbons having at least 5 and up to 8 carbon atoms, said process comprising,a) optionally providing an isomerization zone recovered from the gasoline unit of an oil refinery, b) optionally providing a separation zone capable to treat an hydrocarbon stream comprising branched paraffins and normal paraffins to produce a first hydrocarbon stream having a reduced branched paraffins content and an enhanced normal paraffins content and a second hydrocarbon stream having an enhanced branched paraffins content and a reduced normal paraffins content, c) optionally providing a depentanizer, such that at least two of a), b) and c) are present, wherein, the light naphtha is sent to one of a), b) and c), streams are circulating between the various zones a), b) or c), a stream rich in normal paraffins is sent to the steam cracking unit.
