1. A method for manufacturing microporous carbon material, the method comprising the steps of:
a) in a fluidized bed reactor, fluidizing a granular metal carbide material with a halogen gas or a gas mixture containing a halogen gas at a temperature of including 800° C. up to and including 1300° C.;
b) maintaining a product obtained from step a) at a temperature of including 150° C. to at most 250° C. and under vacuum at a pressure of including 1 mbar to including 300 mbar; and thereafter or subsequently
c) maintaining the product under an atmosphere of a hydrogen gas or a gas mixture containing at least 30% by volume of hydrogen based on a total volume of the gas mixture at a temperature of including 800° C. up to and including 1300° C.; and
d) comminuting the product to a D90 particle size of including 10 μm to including 30 μm and a D10 particle size of including 1.5 μm to 2 μm.
