Researchers at the Chinese Academy of Agricultural Sciences have enhanced hydrogen production from corn straw by using biochar as a pre-catalyst, achieving gas yields over 70% and hydrogen concentrations up to 48.87% by volume. This innovative approach not only improved gas yields by nearly 9 percentage points but also reduced tar production, leading to a net benefit of $0.31 per kilogram of biomass processed. The study highlights the potential for biochar recycling to lower catalyst demand and promote sustainability in biorefineries.
