What Is Carbonation?

Carbonization (carbonization), also known as dry distillation, carbonization, coking, refers to a reaction process in which solid or organic materials are heated and decomposed under the condition of isolated air or heated to produce a liquid or gas (usually a solid) product. This process does not necessarily involve cracking or pyrolysis. The product was collected after condensation. This process requires higher temperatures than usual distillation. Dry distillation can be used to extract liquid fuel from charcoal or wood. Dry distillation can also decompose mineral salts by pyrolysis. For example, dry distillation of sulfate can produce sulfur dioxide and sulfur trioxide, and sulfuric acid can be obtained after dissolving in water. For coal dry distillation, coke, coal tar, crude ammonia, and coal gas can be obtained. (The other "carbonization" is a term that refers to the form of failure of reinforced concrete.)

Basic definition of carbonization

Carbonization

Coal, wood, oil shale, etc. are heated and decomposed into gas (gas), liquid (tar), and solid (coke) products under isolated air. The tar vapor escapes from the coke oven with the gas and can be recycled. Coke is produced from coke. Launched inside the furnace.

Carbonization and carbonization refer to a pyrolysis technology for the purpose of preparing corresponding carbon materials under the conditions of anoxic or deficient oxygen. The process is synchronized with the decomposition of biomass, wood fibers, and lignin.

Carbonization process conditions

Coal, wood, oil shale, etc. are heated under isolated air to decompose them into gas (such as gas), liquid (such as tar) and solid (such as coke) products.

Dry distillation furnace

The dry distillation equipment is generally an industrial furnace and kiln. The gas escapes from the furnace and carries tar vapor, which can be recovered. Coke remains in the kiln. According to the final temperature of heating, it can be generally divided into high temperature dry distillation (about 900 ~ 1100 ), middle temperature dry distillation (about 660 ~ 750 ) and low temperature dry distillation (about 500 ~ 580 ° C). In addition, there are piled carbonization or coal coal carbonization. The relative quantities of gas, liquid, and solid products obtained by retorting vary with heating temperature, time, and pressure. Therefore, changing and adjusting the conditions of the dry distillation process can achieve different production purposes.

Carbonization dehydration carbonization

Dehydration carbonization refers to the removal of organic matter and other elements to leave carbon. For example, concentrated sulfuric acid has a strong dehydration ability. When it comes into contact with organic matter, the hydrogen and oxygen elements in the organic matter are removed according to the composition ratio of water (2: 1), leaving black carbon, thereby carbonizing the other party. The actual removal of hydrogen and oxygen does not mean that the substance contains water.

Other carbonization

Carbonation is a term for concrete failure forms, also known as concrete neutralization. Concrete carbonization means that the concrete itself contains a large number of pores, and carbon dioxide in the air reacts with free calcium hydroxide inside the concrete to form calcium carbonate, causing the concrete to loosen and fall off. After carbonization, the alkalinity of the concrete is reduced. When carbonization exceeds the protective layer of the concrete, in the presence of water and air, the concrete will lose its protective effect on the steel bars, which will cause the steel bars to rust, shrink and crack, and even gel structures.
