HIGH TEMPERATURE GAS REACTIONS. (PART V)
Abstract
Equ pment was developed to study endothermic chemical reactions requiring elevated temperatures and rapid quenches to room temperature. Two reactions were studied with this device in an attempt to produce hydrogen cyanide. One of these reactions, CH4 + !/<N2 gives HCN + 3/2H2 although thermodynamically very favorable at t e temperature levels employed, was fo nd to be too slow to produce HCN in any appreciable quantity. An analysis of the boundary layer flowAROUND THE FILAMENT INDICATED THAT METHANE DECOMPOSES BY A GAS-PHASE PYROLYSIS REACTION. The reaction of ammonia with carbon to prod ce hydrogen cyanide was studied at temperatures of 1900 F. to 3300 F. C + NH3 gives HCN + H2 A comparison of the reactivity of different carbon surfaces for this reaction was obtained by empl ying two different forms of carbon as filaments, a standard electrode grade graphite, and pyr lytic carbon formed from the thermal decomposition of methane at 3500 F. For both types of carbon, the rate o ammonia decomposition into its constituent elements, and the rate of hydrogen cyanide f rmation, were found to be kinetically first order in ammonia. (Author)
