Production and Production-Increasing Factors of Biochar

Abstract

In the article, we deal with biochar-related research and our own developments. Studies in the literature show that biochar can be used as a soil conditioner in agriculture and horticulture. It improves many physical, chemical, and biological properties of the soil and substrate. It increases the water retention capacity while reducing the leaching of nutrients. Through these, you can improve the profit of producers, the sustainability of production, and the efficiency of fertiliser use. By increasing water retention, biochar can reduce irrigation needs and enable production on limited water resources. The developed and presented equipment was called the resting bed (fixed bed) version. Drying and carbonization are also carried out by direct heat transfer. The material, with a temperature equalised by moving drying and a homogeneous composition, enters the reactor. The high-temperature gas and air mixture is introduced into the dryer by a gas jet pump. The energy obtained by burning the pyrolysis gases produced during carbonization ensures the heating of the system, so there is no need for significant external energy input. Due to the structure of the system, the PAH content of the final product is low.
