Description

[0002] Biochar is a solid carbon material obtained by high-temperature pyrolysis or gasification of biomass raw materials (such as wood, straw, fruit shells, etc.). It has a porous structure, large surface area, and strong adsorption capacity. It is often used as a soil conditioner, water treatment agent, solid fuel, etc. In the preparation process of biochar, moisture, volatile organic matter and ash in the raw materials are usually removed to increase the carbon content and calorific value of the carbon. It is an environmentally friendly and renewable resource and is widely used in agriculture, environmental protection, energy and other fields.
