Reaction Kinetics of NH in the Shock Tube Pyrolysis of HNCO (Isocyanic Acid).

摘要

The high temperature kinetics of NH in the pyrolysis of isocyanic acid (HNCO) have been studied in reflected shock wave experiments. Time histories of the NH radical were measured using a cw, narrow-linewidth laser absorption diagnostic at 336 nm. The second-order rate coefficients of the reactions. Isocyanic acid (HNCO) has been used in pyrolysis and photolysis experiments as a source of both the NH and NCO radicals by many investigators. In addition, HNCO decomposition reactions and subsequent reactions of the NH radical are of interest in combustion processes such as fuel-N conversion in flames and the RAPRENOx process. The present study is aimed at measuring the rate coefficients of several reactions important in the pyrolysis of HNCO. Keywords: Combustion. (EG)
