A simplified method has been proposed in the paper of adaptive temperature control in a batch reactor with an exothermal reaction. The control has been effected by a two-level controller enabling the degree of utilization of the cooling capacity of the reactor to be maintained on a present value. The degree of utilization of the cooling capacity was evaluated from the ratio of the time for which the cooling system was in action to that during it was idled. The method has been applied to reactors with a small inertia of the cooling system. The study has been based on the simulation by a mathematical model of the system. Experimental verification of results of the simulation has been caried out a laboratory batch reactor with variable activity of the catalyst.
