The products of biochar pyrolysis include solid char, liquids (water and bio-oil), and gases. Each of these products has distinct characteristics and applications.
Solid Char (Biochar): Biochar is the primary solid product of pyrolysis, consisting of organic matter with high carbon content and ash. The properties of biochar, such as fixed carbon content, pH, higher heating value, and BET surface area, are influenced by the pyrolysis conditions such as temperature and residence time. Biochar is used as a soil amendment to enhance soil fertility, water retention, and carbon sequestration. It can also be sold to recover costs and is marketed as a natural product, qualifying for environmental credits due to its carbon sequestration capabilities.
Liquids: Two main liquid products are produced during pyrolysis: water and bio-oil. Water is a byproduct of both the pyrolysis process and the initial drying stage of the biomass. Bio-oil is a brown, polar liquid composed of a mixture of oxygenated compounds. Its composition varies depending on the feedstock and reaction conditions. Bio-oil has an energy content similar to other commercially produced fuels and can be used for heating, industrial processes, or further refinement into biofuels. Additionally, an aqueous fraction known as wood vinegar is produced, which contains organic acids and other minor components. Wood vinegar has agricultural applications, including plant growth enhancement and insect control.
Gases: The gas products from pyrolysis include carbon monoxide (CO), carbon dioxide (CO2), methane (CH4), hydrogen (H2), and hydrocarbons (CXHY). The composition of these gases depends on the pyrolysis temperature, with higher temperatures leading to the production of more H2 and CXHY gases. These gases can be used as energy sources or for chemical synthesis.
In summary, biochar pyrolysis yields a diverse range of products, each with unique properties and applications. The solid char (biochar) is primarily used for soil enhancement and carbon sequestration, while the liquids (water and bio-oil) and gases have various energy and chemical applications. The process can be optimized to maximize the production of specific products, such as bio-oil for fast pyrolysis, to meet different economic and environmental objectives.
