The physical properties such as moisture content, ash content, volatile matter, fixed carbon and specific surface area were investigated on the spent grain charcoal, Ca(OH)2 added spent grain charcoal and the sawdust charcoal. Moreover, the burning properties of these charcoals were examined.The spent grain charcoal contains fixed carbon of 81 % and ash of 12 %, and the ash content is fairly high compared with that in the sawdust charcoal. The ash content increases to about 16 % when Ca(OH)2 is added to the spent grain charcoal. The ash of spent grain charcoal contains 47 % of P, 22 % of Ca, 14 % of Mg, 13 % of Si and others. The thermal analysis gives a superior information on the ignition and burning properties. The spent grain charcoal is inferior to the sawdust charcoal in the burning property of the ignition temperature and the burning period, because the ignition temperature is higher and the burning period is longer. The addition of Ca(OH)2 to the spent grain improves the burning property of the obtained charcoal due to an increase in the surface area.
