“…Shaub and Bauer (1978) have recently reported results of another computer modeling study of acetylene oxidation behind shock waves. The mechanisms derived in these studies are similar, differing primarily in reactions of CH and CH 2.…”

An analytical study of the ignition of mixtures of methane and ethane has been carried out, using a numerical model consisting of 25 chemical species and 75 elementary chemical reactions. Computed ignition delay times and effective activation energies are compared with published experimental shock tube results. Initial conditions studied include temperatures from 1300-1900 K and mixtures ranging from pure methane to pure ethane, with stoichiometric amounts of oxygen, diluted in argon. The analytical model reproduces experimental results for the effective activation energy and ignition delay time for both pure methane and pure ethane. Ignition delay times computed for mixtures of methane and ethane are found to lie between the pure methane and the pure ethane results. Addition of relatively small quantities of ethane to methane rapidly reduces the ignition delay time of the methane-ethane mixtures to values close to those of pure ethane. The chemical kinetic factors involved in the ignition of fuel mixtures are discussed in detail. The implications of these results for safety studies of liquilied natural gas are also examined.

“…12 Of relevance to the work here is the considerable interest in reactions of C2H in Titan's atmosphere.3~4 Since radical-molecule reactions have been discovered to play an important role in planetary atmospheres and interstellar chemistry, there is a greater need for low-temperature studies of such processes. This laboratory recently reported an extensive low-temperature study of the critical reaction" C,H + C,H, -C4H, + H (1) and its impact on Titan's atmosphere and atmospheric modeling calculations.…”

Rate coefficients for the reaction C2H + 0 2 are measured from 193 to 350 K by using transient absorption spectroscopy with an infrared color center laser. Ethynyl radicals are produced by pulsed laser photolysis of C2H2 in a temperature variable flow cell and a tunable color center laser probesthe transient removal of C2H (R 22+(0,0,0)) in absorption. The rate coefficient has a slight negative temperature dependence over the range 193-350 K which can be expressed as kol = (1.5 f 0.3) X 10-l' exp[(230 f 36)/T] cm3 molecule-' s-l. The lack of a pressure dependence under our experimental conditions strongly suggests that the HCCOO* complex is short lived with respect to encountering a collision and rapidly dissociates to products without competition from collisional stabilization to HCCOO or collisionally induced dissociation to reactants.

“…It has been detected as one of the most abundant species in interstellar space and in planetary atmospheres [1,2]. In addition, C 2 H is known to be an important intermediate in fuel-rich hydrocarbon combustion processes [3]. In a same manner as the H 2 + H system being the prototype of triatomic reactions, the C 2 H + H 2 system plays a similar role for gas phase pentatomic reaction.…”
