Thermal decomposition of n-dodecane: Experiments and kinetic modeling

“…More recently a new study of the thermal decomposition of n-dodecane allowed us to propose a detailed kinetic model made of 1175 reactions involving 175 molecular and radical species [10]. This model was mainly validated from experimental results obtained in a plug flow reactor at higher temperatures (950-1050 K) than the previous papers [7][8][9] and residence times ranging from 0.05 to 0.2 s. In order to get experimental data in a different type of reactor and for a broader range of experimental conditions the new study presented here has been performed using a jet-stirred reactor, which is a well suited apparatus for gas phase kinetic studies [11][12][13][14].…”

“…A very limited work was published about n-dodecane pyrolysis. Zhou et al studied the thermal decomposition of n-dodecane in an unpacked flow reactor at atmospheric pressure and at temperatures from 623 to 893 K [7]. Yoon et al investigated the pyrolysis of pure n-dodecane in a batch reactor at a pressure of 10 bar and at temperatures from 673 to 523 K [8,9].…”

A comprehensive detailed chemical kinetic reaction mechanism for combustion of n-alkane hydrocarbons from n-octane to n-hexadecane

“…As a result, there are numerous studies of conversion of n-alkanes to other chemical species as potential commercial products, and one such study was selected for mechanism validation. In this study by Zhou et al [71], n-alkane thermal pyrolysis, or thermolysis, of n-nonane, n-dodecane, n-tridecane, and n-hexadecane (and n-docosane, n-C 22 H 46 ) and their mixtures were studied at temperatures from 623 to 893 K at atmospheric pressure, in a tubular stainless steel reactor.…”

Retardation of oil cracking to gas and pressure induced combination reactions to account for viscous oil in deep petroleum basins: Evidence from oil and n-hexadecane pyrolysis at water pressures up to 900 bar

“…Fabuss et al, 1964;Ford, 1986;Dominé, 1989;Khorasheh and Gray, 1993a;1993b;Song et al, 1994;Jackson et al, 1995;Behar and Vandenbroucke, 1996). The thermal cracking of aliphatic hydrocarbons involves their conversion into lower molecular weight alkanes and alkenes, and with minor yields of aromatic compounds (Rice, 1931;1933;Voge and Good, 1949;Ford, 1986;Zhou et al, 1987;Bounaceur et al, 2002a) together with branched alkanes of higher molecular weight than the starting alkane. Experimental observations show that the concentration of alkenes decrease with increasing conversion, while the alkanes increase in concentration, especially those with a higher number of carbon atoms than the reactant (Khorasheh and Gray, 1993a;Ford, 1986;Dominé, 1989;Dominé et al, 1990).…”
