Industrial production of activated carbon using circular bioeconomy principles: Case study from a Romanian company
نویسندگان
چکیده
This work discloses an industrial multi-ton scale methodology implemented by a Romanian company (Explocom GK) to use bio-wastes produce biochar, demonstrating case of bio-economy circularity associated with economic growth. The pyrolysis process was able ∼20%w high-quality biochar (550 m2/g) starting from forest-based and agricultural wastes. A fraction ∼60%w is converted into condensates, including wood vinegar, tar, alcohol, etc. that can be recovered purified because the large process. energy contained in volatile syngas produced (∼20%w) stored used instead fossil fuels for heating reactor. Some this vinegar also activate activated carbon (value carbon/value >3, depending on market required properties). transformation increases overall profitability plant while manufacturing product does not or chemicals activation. material locally reduce emissions transport carbons currently exported other continents.

متن کاملProduction of Activated Carbon from
Activated carbon is an adsorbent in the separation and purification industries. The adsorption capacity of activated carbon depends on porosity and its surface chemistry. In this review the production of activation carbon from a large number of abundant and low-cost materials and agricultural waste such as Camellia oleifera shell, bamboo, cherry stones, waste tea, and Paulownia flower are discu...
