Abstract

Abstract We report exclusive continuous gas phase hydrogenation of furfural to furfuryl alcohol over Au/Al<inf>2</inf>O<inf>3</inf> (▵E<inf>a</inf> = 45 kJ mol<sup>- 1</sup>). Characterisation measurements demonstrate the formation of Au<sup>δ -</sup> (from XPS analysis) nanoparticles (1-8 nm, mean = 4.3 nm) with H<inf>2</inf> chemisorption capacity of 318 μmol g<inf>Au</inf><sup>- 1</sup> (at 413 K). Chemical kinetic control was established by experimental variation of contact time, catalyst/furfural feed ratio and temperature. At T ≥ 473 K, hydrogenolysis to 2-methylfuran predominated. Selective TOF (298 h<sup>- 1</sup> at 433 K) over Au/Al<inf>2</inf>O<inf>3</inf> exceeded values reported for benchmark Cu catalysts at higher temperature (453-498 K).
