Sustainable production of hydrocarbon transportation fuels and building-block chemicals from biomass is extremely important to circumvent the development of capital-intensive new infrastructures for automobile sector and petrochemical industry. The present investigation is thus focused on selective conversion of n-butanol to gasoline range transportation fuel, and butylenes and aromatics building blocks in single step. Systematic investigation was carried out in a fixed-bed reactor over HZSM-5 catalyst at atmospheric pressure for clear identification of temperature and weight hourly space velocity (WHSV) window to maximize the yield of various products. The present article additionally provides the mechanistic insights for the formation of various products from n-butanol. © 2016 Elsevier B.V.
