Pyrolysis-steam-reforming of biomass on nano-sized NiZnAlOx gave high yields of H2.
Fresh NiZnAlOx catalysts had well dispersed metal particles of size ∼10–11 nm.
Used catalysts maintained their particle size and showed lowered coke formation.
35NiZn4Al catalyst gave 74.8 wt.% gas yield & maximum H2 (20.1 mmol H2 g−1biomass)
