Our study is focused on thermodynamic analyses and minimization of Gibbs energy for gas de-halogenation (removal of HCl, HF and HBr) by selected solid sorbents (Na2CO3, NaAlO2, CaO/CaCO3, BaO/BaCO3, and mixtures containing CaO-BaO/BaCO3).

The paper summarizes significant fuel-energy and physico-chemical properties of stabilized sewage sludge. Sewage sludge as a fuel is characterized by high proportions of water content, volatile matter content, ash content and a considerable amount of reactive, organic nitrogen (2-5 wt. % of dry matter). In addition to oxygen; silicon, phosphorus, aluminum, iron and calcium are the most abundant elements in the ash from the sludge. The lower calorific value of dry, anaerobically stabilized sewage sludge is 9-12 MJ kg-1 and it corresponds to a low calorific value of lower-class subbituminous coal or lignite.
