FIELD: chemistry.
SUBSTANCE: invention relates to method for conversion of one or more reagents into one or several products in reactor with fluidised catalyst bed, which is inactivated in time. Method includes, in the course of catalytic cycle at stage A, gradual increase of working temperature in reactor to counteract negative impact of catalyst inactivation on rate of reagent conversion, with working temperature not exceeding specified maximal working temperature, and at stage B addition of catalyst, possessing property to increase rate of reagent conversion, into reactor and reduction of working temperature for partial counteraction of impact of added catalyst on rate of reagent conversion, with working temperature remaining higher than specified minimal working temperature, and repetition of A and B stages.
EFFECT: invention provides long-term working procedure for methods, in which catalyst inactivation takes place in the course of time.
