Co-production of porous N-doped biochar and hydrogen-rich gas production from simultaneous pyrolysis-activation-nitrogen doping of biomass: Synergistic mechanism of KOH and NH3<\/sub><\/strong><\/p>\n

Recently, Master student Miss Yu-rou Wang supervised by Dr. Wei Chen and Prof. Zhen Fang<\/strong> published a research article entitled \u201cCo-production of porous N-doped biochar and hydrogen-rich gas production from simultaneous pyrolysis-activation-nitrogen doping of biomass: Synergistic mechanism of KOH and NH3<\/sub>\u201d in Renewable Energy.<\/p>\n

In this study, a method of simultaneous activation and nitrogen doping during biomass fast pyrolysis for co-production of porous N-doped biochar and H2<\/sub>-rich gas production was proposed. The effect of temperature on chemical interaction mechanism of KOH and NH3<\/sub> was investigated at 500-800\u00b0C. Results showed that KOH and NH3<\/sub> had a synergistic effect on pore development and nitrogen doping, and the specific surface area and nitrogen content reached maximum values of 2008.37 m2<\/sup>\/g and 5.05 wt%, respectively. It may be due to that NH3<\/sub> entered pores generating by KOH activation for further activation, and at the same time, excessive NH3<\/sub> could convert new O-containing groups to N-containing groups for more effective nitrogen doping. What\u2019s more, the H2<\/sub> concentration and yield were up to 56.67 vol% and 517.95 mL\/g, respectively. It indicates that the synchronization method of fast pyrolysis-activation-nitrogen doping is a promising approach, which is of great significance for the high-value utilization of biomass.<\/p>\n
