(ASTM method E777-17). The carbon is physically in the form of cellulose, hemicellulose and lignin. When you heat the wood in pyrolysis or gasification you will get about half of the carbon in the form of charcoal. The rest converts to CO, CO2, or other gases. <o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US>Tom <span style='color:black'><o:p></o:p></span></span></p><div><div><p class=MsoNormal style='margin-bottom:12.0pt'><span lang=EN-US><o:p> </o:p></span></p></div><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p></div></div></body></html>
