The Shah refused and nice wooden plates is at 400-500° c. In a low-oxygen gas at State or not at all, or it is to cause incomplete combustion reaction in order to obtain a high amount of carbon.
The carbonization time is to heat the wood at temperatures of 400-500 ° C in the presence of low or no oxygen. That is the cause incomplete combustion reaction to the carbon content.
The carbon carbonized is providing heat to the wood at 400-500 degrees Celsius. In the presence of oxygen gas is low or zero. Or is the reaction incomplete combustion to carbon at high volumes.
