Abstract: The thermal decomposition of urea in the crude KNCO has been studied by DTA and TG techniques. The kinetic parameters were ealeulated according to the obtained rate equations of thermal decomposition of urea. An improved technology has been proposed for the elemination of urea from KNCO.

Key words: KNCO, urea, thermal decomposition, kinetics
