Properties of charcoal made from sawdust composite

The physico-chemical properties of sawdust composite charcoal carbonized with special method are tested and compared with properties of bamboo charcoal .The microstructures and the surface chemical structures of sawdust composite charcoal and bamboo charcoa are analyzed with scanning electron microscopy (SEM)and X-ray diffratometer .The findings show that the physico-chemical properties such as purified degree , fixed carbon and heat value of the sawdust composite charcoal and bomboo charcola are different .Under SEM , it is observed that the microsturcture of the sawdust composite charcoal is totally different from that of solid wood charcoal and bamboo charcoal .Seen from X-ray diffraction diagram, the sawdust composite charcoal , the bamboo charcoal and the wood charcoal have no distinct graphitization structure .[ Ch , 2 fig .1 tab .7 ref .]
