Carbonization dry distillation; carbonization; carbonification also known as dry distillation (dry distillation). Methods for thermochemical processing of solid fuels. Coal, wood, oil shale, etc. are heated and decomposed into gas (gas), liquid (tar) and solid (coke) products under the isolation of air. The tar vapor escapes from the coke oven with the gas and can be recycled. Furnace roll out. The thermal decomposition of organic compounds into carbon and other products in the absence of air, and the dehydration of compounds containing carbon, hydrogen and oxygen (such as sugars) with a strong water absorbing agent (concentrated sulfuric acid) to form carbon is also called carbonization.

During carbonization, the removal ratio of hydrogen and oxygen atoms is 2:1. It refers to a pyrolysis technology of biomass under anoxic or oxygen-deficient conditions for the purpose of preparing corresponding carbon materials. The process is synchronized with the decomposition of biomass, wood fiber and lignin. Carbonization is the same as carbonization. The dehydration of concentrated sulfuric acid is also called carbonization.
