Embodiment 1
[0179] The method for directional production of biomass charcoal by microwave catalytic pyrolysis of biomass provided in the embodiment of the present invention comprises the following steps:
[0180] Select agricultural waste, bamboo charcoal, charcoal, grass charcoal or activated carbon as raw materials;
[0181] The raw materials are pulverized by a pulverizer and passed through a 200-mesh sieve to obtain carbon powder; add a thermosetting adhesive to the carbon powder and stir evenly;
[0182] Put the charcoal powder into a 250-ton hydraulic molding machine for molding, and then dry it in the shade;
[0183] Add the carbon powder to the metal salt or metal oxide catalyst with a mass ratio of 10:0.5~1.5, add the catalyst and mix evenly, then heat to 600°C at a heating rate of 40 / min and perform pyrolysis in a microwave reactor for 40 minutes to obtain a gas product and solid products;
[0184] Quickly condense the gaseous product obtained in the previous step at -4°C, the...
