What is Biochar

生物炭是一种用于土壤修正的木炭。这在碳固换和土壤健康中都很重要。它是一种稳定的固体物质，富含碳，可以在土壤中持续很长时间（例如千年）。与大多数木炭类型相似，生物炭也是由生物质热解制成的。

Moreover, biochar is important in increasing soil fertility (of acidic soil types), increasing soil productivity, providing protection against some soil-borne diseases, etc. We can define biochar as a high-carbon, finely grained residue that is made from the modern pyrolysis process. Here, the direct thermal decomposition of biomass in the absence of oxygen forms a mixture of solids, bio-oil and syngas. The solid residue in this mixture is the biochar. The yield of this pyrolysis depends on the temperature, pressure, residence time, heating rate, etc.

What is Charcoal?

Charcoal is a porous black solid, consisting of an amorphous form of carbon. We can obtain this material as a residue when wood, bone, or other organic matter is heated in the absence of air. There are different types of charcoal, as follows:

Pyrolysis is the process we can use to produce charcoal. It can be done in two ways: the older method and the new/modern method.

The older method of pyrolysis is done using a clamp. In this process, we need a pile of wood logs leaning against a chimney. Here, we need to place the wood logs in a circle, and then we have to cover the logs with soil to avoid air entering the pile. Thereafter, we can light it using a chimney. Then the logs burn slowly and turn into charcoal within a few days.
The modern method of charcoal production is retorting. Here, heat is recovered from and solely provided by the combustion of gas released during carbonization.

根据木炭的来源，我们可以将其分为几种形式，例如

Common charcoal that is made from wood, peat, petroleum, etc.
Sugar charcoal that is made from carbonization of sugar.
活性木炭是通过在某些气体存在的情况下加热普通木炭制成的，这些气体会导致在引起吸附的表面上形成“孔”。这种类型是制造的，尤其是用于医学和研究用途。
Lump charcoal made by burning hardwood material. This is also named as traditional charcoal.

考虑使用木炭时，它最重要的是燃料。木炭对铁匠很有用，因为木炭在较高温度（例如2700）处燃烧^oC. As an industrial fuel, charcoal is used for smelting of iron. A more common use of charcoal, especially activated charcoal, is its use for purification purposes. Activated charcoal readily adsorbs chemical compounds such as organic impurities. Charcoal can also be used as a source of carbon in chemical reactions.

What is the Difference Between Biochar and Charcoal?

炭是一种物质,是高碳,一个d it is obtained via the pyrolysis of biomass in the absence of oxygen. Biochar is a type of charcoal that is used for soil amendment. The key difference between biochar and charcoal is that biochar is a type of charcoal that is made via the modern pyrolysis method, whereas charcoal is produced either from the older method or from the modern method.

概括– Biochar vs Charcoal

Biochar is a type of charcoal. The key difference between biochar and charcoal is that biochar is a type of charcoal that is made thought the modern pyrolysis method, whereas charcoal is produced either from the older method or from the modern method.
