The technology of anaerobic pyrolysis kilns in biochar (BC) production has demonstrated success and efficiency in recent years. Research shows that the structure of the pyrolysis kiln consists of a kiln body and a lid. The kiln body is robustly designed to withstand high pressure and temperature. The lid incorporates a condenser and activated carbon, which serve to process gases such as CO2, CH4, CnHn, etc., ensuring no air pollution. Moreover, experimental studies have outlined the “biochar production process” using anaerobic pyrolysis kilns, which includes five steps: (i) raw material preparation, (ii) raw material preprocessing, (iii) biochar burning/firing, (iv) biochar cooling, and (v) biochar preservation and storage. Notably, the biochar production process using pyrolysis kiln technology generates a by-product called wood vinegar, a type of “pyroligneous acid” solution that benefits the environment and offers commercial value. This is considered a “green” product with promising potential applications in the future.
