ABSTRACT:
Low boiling paraffinic feedstreams such as solvent raffinates and straight run naphthas are disproportionated in the presence of an intermediate pore size zeolite such as ZSM-5 under conditions of moderately elevated temperatures and pressures to produce products boiling in the middle distillate range, such as jet fuel and diesel fuel, of highly paraffinic character.
