Biochar activation
WebIn this work, different biochar-based metal catalysts were tested for mid-temperature (400−600 °C) acetic acid steam reforming. K, Co, Ce, Fe and Ni were chosen as active phases for the production of the studied catalysts. Their performance was evaluated in terms of acetic acid conversion, hydrogen yield, acetone yield, and stability.
