•Ethanol converts to hydrocarbons over H-ZSM-5 based zeolite catalysts.•P addition decreases ethanol conversion and ethylene overconversion activities.•Ni addition enhances C4 and aromatic selectivity.•Fe addition enhances light olefins formation.•Selectivity can be tuned by doping.
Conversion of ethanol to hydrocarbons was investigated over H-ZSM-5 zeolite and its modification by addition of phosphorus, iron and nickel. Reaction is realized in a tubular flow reactor at atmospheric pressure. Catalyst characterization was performed by UV–vis, TG–DTA, XRD, NH3-TPD, and IR spectroscopy of the surface OH groups and of adsorbed pyridine. High P content enhances the selectivity to lower olefins, in particular ethylene, as also occurs in the case of Fe addition. Over Ni-modified zeolites, C4 and aromatic production is promoted. The role of acidity on the conversion path is briefly discussed.
