Technologies for energetic exploitation of biodiesel chain derived glycerol: Oxy-fuels production by catalytic conversion

► A glycerol conversion in an oxy-fuel for diesel engine has been proposed. ► Hyflon® based catalysts supported on spherical silica have been developed. ► The impact of the oxy-fuel on the engine emissions and performance has been described. ► LCA of the oxy-fuel/diesel blend shows a lower impact that the one of neat diesel.
