PROVIDED ARE A METHOD AND AN APPARATUS FOR PRODUCING PALM KERNEL SHELL 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 (3) IN WHICH SELF-SUSTAINING COMBUSTION CAN PROCEED. THE METHOD FOR PRODUCING PALM KERNEL SHELL CHARCOAL ACCORDING TO THE PRESENT INVENTION CARBONIZES PALM KERNEL SHELL (PKS) USING A DIRECT HEATING TYPE ROTARY KILN (3) IN WHICH SELF-SUSTAINING COMBUSTION CAN PROCEED, AND IS CHARACTERIZED BY INCLUDING A STEP OF CARBONIZING THE PALM KERNEL SHELL USING THE ROTARY KILN (3), AND A STEP OF REMOVING VOLATILE MATTER CONTAINED IN THE PALM KERNEL SHELL CHARCOAL UTILIZING SENSIBLE HEAT OF THE PALM KERNEL SHELL CHARCOAL BY PLACING THE HOT PALM KERNEL SHELL CHARCOAL THAT HAS UNDERGONE THE CARBONIZATION STEP IN A HEAT-INSULATED CHAMBER (5) IN WHICH AIR FLOW IS RESTRICTED AND HOLDING THE PALM KERNEL SHELL CHARCOAL THEREIN FOR 30 MINUTES OR MORE. |
