Abstract

Delay of ignition (tau) of mixtures of hydrogen with nitrous oxide measured in a static bypass apparatus and from reflected shock waves at 850 to 2000/sup 0/K and (N/sub 2/O)/(H) = 0.17 to 3. The value of tau virtually does not depend on the hydrogen concentration and varies inversely with the N/sub 2/O concentration. By comparison of measured tau with results of calculation using the theoretically obtained analytical expression of tau as a function of thermophysical and kinetic characteristics of the system, the necessity was substantiated of introducing into the chain-reaction scheme a linear termination step N/sub 2/O + H ..-->.. NH + NO (6), the rate constant of which is expressed as k/sub 6/ = 10/sup 14.8 +- 0.3/ exp (-(29.0 +- 1.5/RT)), cm/sup 3//mole.sec. 2 figures, 1 table.

Mechanism for the combustion of methane-oxygen mixtures in the presence of added N/sub 2/O

Journal Article Borisov, A; Dragalova, E; Zamanskii, V; ... - Kinet. Catal. (Engl. Transl.); (United States)

The combustion delays (tau) of fuel-depleted and stoichiometric methane-oxygen mixtures with from 5 to 40% added N/sub 2/O were measured in a steady-state bypass system and in reflected shock waves at 880 to 1880/sup 0/K. In the presence of significant amounts of N/sub 2/O, the formation of active species in the CH/sub 4/-O/sub 2/ chain reaction occurs largely in the decomposition of nitrous oxide: N/sub 2/O+M ..-->.. N/sub 2/+O+M, whose rate is known reliably in a wide range of conditions. The introduction of a new initiation reaction permits a significant simplification of the reaction mechanism.

Removal of NO sub x from flue gases using the urea acidic process; Kinetics of the chemical reaction of nitrous acid with urea

Journal Article Lasalle, A; Roizard, C; Midoux, N; ... - Industrial and Engineering Chemistry Research; (United States)

This paper deals with the removal of nitrogen oxides from flue gases using the acidic urea process. The chemical hydrolysis of nitrous acid, which leads to NO formation, is avoided by nitrous acid reaction with urea. Products of this reaction are gases, e.g. CO{sub 2} and N{sub 2} which can then be directly released into the atmosphere. The aim here is to determine the kinetic parameters of the chemical reaction of nitrous acid with urea. Experiments are performed in a closed stirred reactor. The manometric method (measurement of the pressure versus time curve) leads to the determination of the concentrationmore »« less

Thermal reactions of pyrrolidine at elevated temperatures. Studies with a single-pulse shock tube

Journal Article Lifshitz, A; Bidani, M; Agranat, A; ... - J. Phys. Chem.; (United States)

The thermal decomposition of pyrrolidine was studied behind reflected shocks in a single-pulse shock tube over the temperature range 900-1400 K and overall densities of approx. 3 x 10/sup -5/ mol/cm/sup 3/. Under these conditions the following reaction products were found in the postshock mixtures: H/sub 2/, CH/sub 4/, C/sub 2/H/sub 4/, C/sub 2/H/sub 6/, C/sub 2/H/sub 2/, C/sub 3/H/sub 6/, CH/sub 2/=C=CH/sub 2/, CH/sub 3/C identical with CH, CH/sub 2/=CHCH/sub 2/CH/sub 3/, HCN, CH/sub 3/CN, CH/sub 2/=CHCN,C/sub 2/H/sub 5/CN, and small quantities of pyrrole and butadiene. Studies with a mixture of pyrrolidine and pyrrolidine-d/sub 9/ show that C/sub 2/H/submore »« less

Shock tube study of ignition delay times in methane--oxygen--nitrogen--argon mixtures. [N/sub 2/ effects on ignition delay of CH/sub 4/--O/sub 2/ mixtures]

Journal Article Grillo, A; Slack, M - Combust. Flame; (United States)

Ignition delay times have been measured in homogeneous CH/sub 4/-O/sub 2/ and CH/sub 4/-O/sub 2/-N/sub 2/ mixtures dilute in argon, in order to investigate the influence of molecular nitrogen. The mixtures were heated behind reflected waves in a conventional shock tube to temperatures between 1640 and 2150/sup 0/K at pressures from 1 to 6 atm. Equivalence ratios of 1.0 and 2.0 were investigated and the methane concentration ranged from 1 x 10/sup -7/ to 9 x 10/sup -7/ mole/cc. Ignition was identified from photometric observations of OH (3064 A), H/sub 2/O (2.7 ..mu..) and CO/sub 2/(4.3 ..mu..) emission. For bothmore »« less

Hydrogen/nitrous oxide kinetics -- Implications of the N{sub x}H{sub y} species

Journal Article Allen, M; Yetter, R; Dryer, F - Combustion and Flame

Nitrous oxide, hydrogen, and species containing NH bonds (such as NH{sub 3}, NH{sub 2}, and NH) actively participate in the gas-phase chemistry above burning solid propellants. Dilute mixtures of hydrogen and nitrous oxide in nitrogen were studied in a large-diameter flow reactor at 3 atm and 995 K. The consumption of H{sub 2} and N{sub 2}O as well as the formation of H{sub 2}O and the intermediate species profiles of NH{sub 3} and NO were all measured experimentally. A detailed chemical mechanism is developed and compared with the experimental measurements. From knowledge of the NH{sub 3} and NO intermediate speciesmore »« less
