Biochar is carbon using a microscopic honeycomb structure with the real size of the pore spaces dependent on the kind of biomass used and the process of pyrolysis. This honeycomb structure is excellent for both holding water, supplying micro-habitat for microbial activity and improving nutrient exchange between the soil and plant roots.
Biochar is a fancy title for charcoal, coined due to the particular use of charcoal as a soil amendment rather than as a fuel. Like charcoal, biochar is the solid material left behind when organic material is burnt in low levels of oxygen. This can occur naturally like when belowground peat deposits burn but more commonly is engineered by people in special combustion chambers via a process called pyrolysis.Browse http://www.kmuch.com/ if you want to learn more about Importance Of Biochar.
What happens from pyrolysis is that instead of combust completely to ash, as when we burn wood in an open fire, there isn’t enough oxygen for all of the organic material to burn. Rather the organic material creates a watertight black material that’s all but complete carbon, the char, and liquid gas products.
When biomass smolders for a long time at low temperatures it creates mostly char and when the temperature of pyrolysis is greater and the procedure quicker more gas is produced.
The true structure of the char resembles a honeycomb with air pockets between a fine matrix of carbon atoms.
How to Earn biochar
Creating biochar is simple enough in principle. You require a source of organic material which could be nearly anything from dead plants to animal waste. It can be dry or wet so long as there is enough organic matter to support combustion.
Then some unit is necessary for which to burn the organic matter in low oxygen which can be as straightforward as a trench in the ground covered with leaves, or a kiln on the rear of a truck, all of the way to some full-scale industrial center.
From the industrial version organic substance, that the engineers could call the feedstock, is dried and fed into a kiln and burnt in low to no oxygen at temperatures between 400 and 700 Celsius. More char is created in the lower temperatures.
The challenge in manufacture is to get a constant source of feedstock to make it easier to keep the desired conditions together with the combustion chamber and maintain production.
Biochars Are made from
Timber and wood chips
bagasse (sugarcane waste)
Every sort of organic material requires certain conditions for successful biochar pyrolysis. The wetter the substance the harder it’s to keep the combustion. As a guideline around 40 percent by weight of the organic substance into ends up as char.
Industrial production could be achieved in which the feedstock (biomass materials) could be transported to a central facility and processed. These facilities usually operate to create gas and char, where the gas is further combusted to generate electricity.
An alternative approach is to utilize vehicle mounted kilns that can move between biomass resources, like from one farm to another. Present equipment can process up to 450 kg of biomass per hour.
Why is biochar useful?
When a plant grows it uses water and nutrients in the ground. Nice roots grow into the very small spaces between the soil particles and nutrients flow across from the groundwater to the cells from the roots. It’s a world we can’t see that’s determined by microbial activity in those little soil spaces.
