Effects of calcium carbonate on pyrolysis of sewage

This study demonstrates that calcium carbonate (CaCO 3) allows not only enhancement of the production of CO as syngas, but also reduction of the content of polycyclic aromatic hydrocarbons (PAHs) in the pyrolytic products from sewage sludge.CO 2 was formed by the decomposition of CaCO 3 in pyrolysis. The CO 2 derived from CaCO 3 enhanced thermal cracking of volatile organic carbons (VOCs
