Contributions to the mechanism of NH_3 thermal decomposition

摘要

The kinetic parameters (reaction order, rate constant, activation energy) were calculated by processing on a computer by applying differential and integral methods for the temperatures of 700℃ and 800℃. The values of the kinetic parameters were found to depend on the ammonia flow rate, which supports the hypothesis of the ammonia consumption in the decomposition reaction proceeding as a chain reaction. The agreement between the theoretical and experimental values of the rate constant and activation energy also sustains this hypothesis.
