“…Besides, ethylene is an important precursor of PAHs and soot, which can undergo simultaneous dehydrogenation in the gas phase to generate PAHs and soot via the hydrogen abstraction acetylene addition (HACA) route. 36,37 In this work, the decreased yield of ethylene as a function of temperature (Fig. 3) is consistent with the increased soot (Fig.…”

Thermal decomposition of the two light polycyclic aromatic hydrocarbons (PAHs) naphthalene and anthracene as tar model compounds was investigated with a lab-scale fluidized bed reactor. Pyrolysis kinetics for the four main gaseous products, namely hydrogen, methane, ethylene and propane, were evaluated. Experimental results indicated that naphthalene with two fused benzene rings was easier to be decomposed than anthracene with three fused benzene rings. , respectively. The most probable reaction mechanisms describing the evolution profiles of individual gas components from the pyrolysis of the two PAHs were three-dimensional diffusion for hydrogen, methane, and propane, as well as chemical reaction for ethylene.

“…molecules of the formula Si x C y H z where x, y and z are all ≥1, in the growth process. It is reasonable to anticipate that the chemical routes for formation of organosilicons will be different for methane and for hydrocarbon molecules with one or more C-C bonds, which have different pyrolysis chemistry [11,12]. The route for formation of organosilicons from methane might be less efficient leading to a lower amount of organosilicons available for SiC growth when methane is used as carbon precursor.…”

Abstract:It is generally considered that methane is not a suitable carbon precursor for growth of silicon carbide (SiC) epitaxial layers by chemical vapor deposition (CVD) since its use renders epitaxial layers with very high surface roughness. In this work we demonstrate that in fact SiC epitaxial layers with high-quality morphology can be grown using methane. It is shown that a key factor in obtaining high-quality material is tuning the C/Si ratio of the process gas mixture to a region where the growth is limited neither by carbon nor by silicon supplies. From the growth characteristics presented here, we argue that the reactivity of methane with the SiC surface is much higher than generally assumed in SiC CVD modeling today.

“…Finally, several authors proposed interesting but partial results due to incomplete species quantification. As an example, Murphy et al [84] pyrolyzed different small hydrocarbons, including methane, in a flow system. Little information was given about the product distribution: methane decomposition, ethylene and acetylene productions (expressed in mol%).…”
