The invention discloses a nitrogen-rich biomass-based activated carbon with a multi-level porous micro-channel structure and an application thereof, belonging to the technical field of porous carbon materials. The invention provides a nitrogen-rich biomass-based activated carbon with a hierarchical porous microchannel structure in order to solve the problems of low nitrogen doping amount and damaged microchannel structure in the current nitrogen-doped activated carbon. The preparation method is as follows: biomass , melamine cyanurate or its mixed nitrogen source and activator are mixed in water, dried, ground and sieved, then heated to 650-950 ℃ in an inert atmosphere for calcination, washed and dried to obtain. The nitrogen-rich biomass-based activated carbon with the hierarchical porous microchannel structure of the present invention has high specific surface area, high total pore volume, hierarchical porous structure, high nitrogen content and high surface nitrogen content, less activator dosage and low microporosity and other characteristics, with excellent desulfurization and decarbonization performance. |
