摘要： A process for producing graphite in a vertical graphitization furnace having at least one process chamber that bounds a heating zone, a temperature of 2200° C. to 3200° C. is generated in the heating zone, particulate graphitizable material is supplied to the process chamber through an inlet, graphitizable material is conveyed through the heating zone of the process chamber, in which it is graphitized to graphite, and graphite obtained is removed from the process chamber through an outlet. In some variants, graphitizable material wherein the particles have a particle size of less than 3 mm is used, and/or, a material column is formed throughout the heating zone of a particular process chamber, wherein graphitizable material, after being supplied through the inlet from the top, trickles through an intake zone of the process chamber onto the material column, and/or, a material column is formed in a stationary heating zone of a particular process chamber encompassed by the heating zone, wherein graphitizable material, after being supplied through the intake from the top, trickles through a drop heating zone likewise encompassed by the heating zone onto the material column, and/or, graphitizable material in one or more material vessels is conveyed through a particular process chamber and through the heating zone thereof. Also specified is a vertical graphitization furnace optimized.
