Abstract: In a way to explore the inherent acidity and porosity properties of zeolites for the conversion of renewable biomass-derived ethanol into various fuel stocks, three types of zeolites; HZ, HY, and HB have been studied in their proton form. The studies indicated the formation of catalyst-dependent hydrocarbon composition of the product falling in gasoline and jet fuel for the specific end-use applications. The flexibility in product choice facilitated by changing the catalyst makes the present process suitable for industrial applications based on the nature of product in demand. At optimized temperature and pressure reaction conditions, HB zeolite produced >40 wt% jet fuel hydrocarbons (T = 400 °C and P = 50 bar), HZ produced 53 wt% octane gasoline (RON >100) and HY zeolite produced 25 wt% of olefins in liquid product. The novelty of the present process lies in its simple, single-step, continuous-flow vapour-phase single catalytic process operating on zeolites bearing no metal function but possessing variable pore size and other catalytic properties required for producing higher range hydrocarbons from ethanol.
