In an attempt to conduct an effective conversion of bioethanol into gasoline rich in aromatics and iso-paraffins, a ZSM-5 type zeolite with special features such as nano crystalline size and acidity has been synthesized. The catalyst (NZ) exhibits highest gasoline yield of about 73.8 wt % with aromatics and iso-paraffins as major components. The product measures Research Octane Number (RON) of about 95, which is desirable for the gasoline specifications. Moreover, considerable amounts of the Liquefied Petroleum Gas (LPG) (15 wt %) and light olefins (14 wt %) are also formed as by-products that add value to the process. The nano crystalline ZSM-5 catalyst (NZ) exhibits the stability in activity in terms of bioethanol conversion and aromatics yields for the reaction time period of 40 h.
