A clean stream of alkanes from renewable biomass resources is obtained through aqueous‐phase reforming in a single reactor. Alkanes are produced from biomass‐derived sorbitol through a bifunctional pathway (see scheme) that involves the dehydration of sorbitol on acid sites (SiO 2 /Al 2 O 3 ) and hydrogenation of intermediates on a metal catalyst under a H 2 atmosphere. Hydrogen is produced from sorbitol and water on the metal catalyst in the same reactor.
