Carbonization is also called dry distillation. Thermochemical processing method of solid fuel. Coal, wood, oil shale, etc. It is decomposed into gas, liquid and solid products by heating under the condition of air isolation. Tar vapor escapes from the coke oven with gas and can be recycled, while coke is pushed out of the coke oven.

Carbonization and co-carbonization refer to a pyrolysis technology of biomass under anoxic or anoxic conditions, with the purpose of preparing corresponding carbon materials. The process is synchronized with the decomposition of biomass, lignocellulose and lignin.

Extended data:

Organic compounds are thermally decomposed into carbon and other products under the condition of air isolation. Compounds containing carbon, hydrogen and oxygen (such as sugar) are dehydrated into carbon with strong water absorbent (concentrated sulfuric acid), which is also called carbonization.

Carbonization process conditions:

Coal, wood, oil shale, etc. It is heated in isolation from air, so that they can be decomposed into gas (such as gas), liquid (such as tar) and solid (such as coke) products. Dry distillation equipment is generally an industrial furnace, and gas escapes from the furnace with tar vapor, which can be recovered.

The coke is left in the stove. According to the final temperature of heating, it can be generally divided into high temperature retorting, medium temperature retorting and low temperature retorting. In addition, there are pile dry distillation or coal pile dry distillation. The relative amounts of gas, liquid and solid products obtained by dry distillation change with the change of heating temperature, time and pressure. Therefore, changing and adjusting the conditions of dry distillation process can achieve different production purposes.
