Disclosed are a method and a device for producing a palm kernel shell (PKS) charcoal, said PKS charcoal having a fixed carbon content of 80% or more and a volatile matter content of 12% or less, using a direct heating type rotary kiln in which self-sustaining combustion can proceed. The method for producing a PKS charcoal, whereby PKS is carbonized by using a direct heating type rotary kiln in which self-sustaining combustion can proceed to give the PKS charcoal, is characterized by comprising a carbonization step for carbonizing the PKS by using said rotary kiln, and a volatile matter-removal step for removing volatile matters contained in said PKS charcoal with the use of the potential heat thereof by, after the carbonization step, enclosing the hot PKS charcoal in a heat-insulated chamber with restricted air flow and holding the PKS charcoal therein for 30 minutes or longer. Cette invention concerne un procédé et un dispositif de production de charbon à base de coques de noix de palme (PKS), ledit charbon PKS ayant une teneur en carbone fixe de 80 % ou plus et une teneur en matières volatiles de 12 % ou moins, à l'aide d'un haut-fourneau rotatif de type à chauffage direct permettant une combustion auto-entretenue. Le procédé de production d'un charbon PKS, qui consiste à carboniser des PKS dans un haut-fourneau rotatif de type à chauffage direct permettant une combustion auto-entretenue et l'obtention du charbon PKS, est caractérisé en ce qu'il comprend une étape de carbonisation qui consiste à carboniser les PKS dans ledit haut-fourneau rotatif, et une étape d'élimination des matières volatiles contenues dans ledit charbon PKS à l'aide de sa chaleur potentielle par confinement, après l'étape de carbonisation, du charbon PKS chaud dans une chambre calorifugée bénéficiant d'un flux d'air restreint et maintien du charbon PKS dans ladite chambre pendant 30 minutes ou plus.
