Abstract

On the basis of earlier received of process of decomposition in thedevice of periodic action the mathematical model of process of decomposition in a flow reactor of full hashing in view of input of a priming in a feed is made. On the basis of the received model in a flow reactor the mathematical model of process of decomposition in the cascade of 14 rectors flow type has been developed. Models are made in the inveroment of program complex ReactOp. The solution of the equation of model has been carried out by a stabilization method.
