Catalytic Combustion Processes

Abstract

This work presents experimental data on the effect of catalytic additives on the combustion characteristics of ammonium nitrate and per-chlorate and the explosives of different classes. Burning rates are determined photographically in a constant pressure bomb within a broad range of pressure: from the lower limit up to 1000 atmospheres. The ratio, K, of the catalyzed, R m , to the uncatalyzed, R o , mass burning rate under the same conditions is used as a criterion of the efficiency of the additive. The upper and lower limits of manifestation of the catalytic effect of inorganic and metallorganic additives are determined and the corresponding diagrams, K(Ro), are drawn. An equation of catalysis in the form of K = ARo is used to present the data. The general aspects and principles of positive and negative catalysis during the combustion of condensed and gaseous systems and the arbitrary nature of the "combustion catalyst" concept are considered.
