Research on intregrated manufacture of charcoal and wood vinegar was alreatfy carried out in the modified kiln constructed of double drum combined with a condensing technique device, therel: Jyielding not only charcoal but also concurrent!J distillateliquid or the so called wood vinegar (liquidsmoke). The kiln operated IJJith a batch system, and the raw materialfor such was astesfrom wood processing industries. This researchaims to look intothe manufacturaes well as qualities of charcoal and wood vinegar bothproduced concu entlyusing the double drum type carbonization kiln, and smltinize theprospective usesof the latterprodua. Resultsrevealedthat the kilnturned out as much as 6.00-15.00 kg of charcoaland 2.40-4.40kg of wood vinegar. Based on theinputcharge of raw material, the charcoaiyieldreached9.90-21.08%, and wood vinegaryield 4.95 - 7.3 5%. The chemicalcomponents in wood vinegar as identified using highperformance liquid chromatograplny (HPLC)and gas chromatograplly (GC)consisted of consecutively acetic acid (21.31ppm- 30.05 ppm), methanol (0.44% -1.15%) and phenol (52.41 ppm - 63.26 ppm).Results of anaflsisusingGCM.S(aschromatograplly-mass spectrometry) pyrolisis exhibited that the wood vinegaryielded l:J each species of wood waste contained as many as 20-32 chemical components, which differedfrom one species to another. The nutrient elements in the resultingwood vinegar comprised C organic(6.12- 7.35%), N total(0.62-0.67%), P,01total(0.24-0.31%,), and K,0 total(0.31-0.36%).Usesof wood vinegar were numerous, among othersasfoodpreservative,pesticideandplantdiseaseremetfy,organic liquidfertilizer,plant f erlilizer, disinfectantand inhibitorfor microorganisms,andfungiand bacteriaprevention.
