METHOD AND DEVICE FOR PRODUCING PELM KERNEL SHELL CHARCOAL

WIPO Patent Application WO/2011/142001

A1

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.
