A commercial limestone was used in aqueous suspension to capture SO2 from coal combustion gases in a bench scale system. To evaluate the limestone absorption capacity during the applied process, a new method was developed by thermogravimetry (TG), wh

The WTPs generate a residue in decanters called sludge, which, despite having a similar chemical composition of clay minerals, does not behave as such when embedded in such clays. Several surveys conducted indicate a decrease in Flexural Strength for

A study by thermogravimetry was done to evaluate the influence of the particle size on the pozzolanic activity of a residual equilibrium catalyst from a fluid catalytic cracking unit of a Brazilian refinery. For this purpose, cement type II pastes wi
