Abstract
Processes for reforming of naphtha feedstocks are described. Briefly, a two stage naphtha reforming process is described. The first stage uses a low acidity beta zeolite catalyst under relatively mild reforming conditions to form an effluent. This effluent is passed to a subsequent stage where further reforming occurs using a catalyst containing ZSM-5 zeolite. The second stage is run under mild reforming conditions. The low pressures employed in the reforming process described maximize liquid product yield by avoiding unwanted cracking reactions and production of light products.
