Patent ID: 7575668

Claim:
A process for the conversion of a kerosene feedstock to produce naphtha and isobutane which process comprises: (a) reacting the kerosene feedstock and hydrogen in an aromatic saturation reaction zone containing a noble metal catalyst to produce a liquid hydrocarbon stream having a reduced concentration of aromatic compounds; (b) recycling at least a portion of the liquid hydrocarbon having a reduced concentration of aromatic compounds to the aromatic saturation reaction zone; (c) passing at least a portion of the liquid hydrocarbon stream having a reduced concentration of aromatic compounds into an adsorption zone containing an adsorbent to remove hydrogen sulfide and water; and (d) reacting a resulting dry hydrocarbon stream produced in step (c) and hydrogen in a hydrocracking zone containing a noble metal on chlorided alumina hydrocracking catalyst to produce naphtha and isobutane.
