The Cool Flames of Hydrocarbons

Abstract

This review describes the properties of the cool-game and two-stage ignition processes

The role of in situ reforming in plasma enhanced ultra lean premixed methane/air flames

“…The preflame observed in this study has a resemblance to a socalled ''cool flame" sometimes seen in conventional combustion studies [35]. General and specific comparisons between the preflame seen here, and cool flames are made in Table 2, These two flames share several common characteristics, including perhaps the most significant -low temperature partial oxidation reactions to produce H 2 and CO as their main products.…”

“…General and specific comparisons between the preflame seen here, and cool flames are made in Table 2, These two flames share several common characteristics, including perhaps the most significant -low temperature partial oxidation reactions to produce H 2 and CO as their main products. Both flames have temperatures that fall within a similar range of values, with the preflame found to be approximately 600 K, according to the simulations, and cool flames falling within the range of 500-800 K [35]. In addition, like cool flames, the preflame seems to be ''volume filling" [17] and is not sheet-like in its geometry.…”

Gas‐phase oxidation of 1,4‐dioxane

“…The main primary elementary steps which can be written a priori, in case of a chain radical mechanism of slow oxidation of l,Cdioxane, taking into account the present knowledge on the oxidation of organic compounds either obtained in our laboratory [7,8] or published in the literature [9], are represented in Figure 6. The thermochemistry of these steps is given in Table I and estimates of the relevant rate constants obtained by the techniques of Thermochemical Kinetics [lo] are given in Table 11.…”

A theoretical study on the reaction mechanism of O2 with C4H9• radical

“…Deep understanding on the combustion reaction mechanism of hydrocarbon is an urgent scientific goal [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17], and investigations on the reactions of reactive species such as hydrocarbon radicals can provide significant insights into combustion, hydrocarbon synthesis, interstellar space, and atmospheric chemistry. The reactivity of radicals which is very different from closed-shell molecules is extremely important in the reactions, e.g., between oxygen and hydrocarbon radicals.…”
