Abstract
The spent catalyst from the ammonia synthesis was chemically and techn ologically characterized and the kinetics of its decomposition with su lphuric acid was experimentally studies, at laboratory scale. The resu lts got showed that the acid temperature and concentration have a favo urable influence upon the solid solubilization rate. The graphical pro cessing of the data showed that the process takes place in the transfo rmation range (Ea = 45...67,4 kJ/mol) the kinetic order depending on t he sulphuric acid excess only, as per the relation n = e(0.03E+0.5056) .
