Description
Introduction of Wood Biochar
Wood biochar is a solid or semi-solid product that mede from wood through pyrolysis or gasification, it has highly aromatic and graphitized properties, high carbon content and the ability to fix nitrogen.
It has a wide range of renewable sources of raw materials. Wood biochar is porous and has a high specific surface area after treatment, which can adsorb nutrients and water in the soil, increase the nitrogen content and fertility of the soil, improve the soil structure and increase the resilience of the soil.

Features
Characteristics of Wood Biochar
Wood biochar is made from wood chips, bark, straw and other waste materials. These raw materials are abundant and recycling can reduce environmental pollution.
Biochar has developed pore structure, huge specific surface area and strong adsorption properties.
It has a wide range of applications, including coal chemical industry, petrochemical industry, waste gas treatment and so on. In addition, wood biochar can be repeatedly regenerated by methods such as physical, chemical and biological regeneration, making it a sustainable carbon material.
Syngas Desulfurization and dechlorination：As an efficient gas adsorbent, wood biochar can remove harmful impurities such as hydrogen sulfide and chlorine in syngas, improve the quality of syngas and the purity of products.
VOCs exhaust gas control：Through the use of wood biochar and other adsorbents, effectively remove VOCs waste gas in the air, protect the environment and human health.
Liquid phase adsorption
Sewage treatment depth treatment: Wood biochar is used to further remove harmful substances from water and improve water quality and environmental quality.
Organic solvent recovery: The absorbents such as wood biochar are recovered and treated to realize the win-win situation of resource utilization and environmental protection.
Organic Solvent Recovery
Benzene series gas recovery: Recovery of benzene gas toluene and xylene, recovery of CS2 in viscose staple fiber production, etc.
Other organic solvent recovery: Recovery of other organic solvents with high recovery value.
In general, wood biochar is an environmentally friendly material with wide application prospects, and its development and application help to promote the recycling of resources and environmental protection.By further refining the application field of wood biochar, we can better understand its advantages and application range, and provide a valuable reference for future research and application.
