Durian, known as the "king of fruits", is loved by many diners around the world for its unique flavor and high nutritional value. However, while enjoying the delicious taste of durian, we often ignore one problem - the treatment of a large number of durian shells. In the traditional concept, durian shells are often regarded as useless waste, which causes environmental pollution and is also a waste of resources. As a biomass raw material, durian shells can also be used to process biochar.
First of all, let's talk about the characteristics of durian shells. Durian shells are hard and have a unique fiber structure, and durian shells are rich in cellulose, hemicellulose and lignin, which are common raw materials in biomass energy.
Durian shell charcoal making process.
Pretreatment: First of all, the durian shell should be dried to reduce the moisture to improve the charcoal making efficiency and carbonization quality.
Crushing: The dried durian shell is crushed to make it reach a suitable size, which is convenient for the subsequent carbonization process.
Carbonization: Put the crushed durian shell into the carbonization furnace and heat it to a certain temperature (usually between 300 -600) under the condition of lack of oxygen or micro-oxygen, so that it undergoes pyrolysis reaction and is converted into charcoal.
Cooling and packaging: After the carbonization is completed, the biochar needs to be cooled to room temperature and properly packed for easy storage and transportation.
Application of durian shell charcoal.
The durian shell charcoal produced has good adsorption properties, high calorific value and stable chemical properties, which can be widely used in the following fields:
Water treatment: used as an adsorbent to effectively remove impurities and contaminants in water.
Air purification: Use its adsorption properties to remove harmful gases and odors from the air.
Agriculture: As a soil amendment, it increases the air permeability and water retention of the soil and promotes plant growth.
Energy: Due to its high calorific value, it can be used as a clean fuel.
In conclusion, the reuse of durian shells is not only in line with the concept of environmental protection and sustainable development, but also brings economic benefits. Transform this seemingly useless "waste" into a valuable resource.
