“…to room temperature in less than a millisecond? The quenching probe performs this rapid cooling (8,29). Giving consideration to the chemical stability of the transient species, it could be expected that some would be preserved upon quenchinge.g., N2-but that others would undergo reaction with the 50 mole % concentration of atomic fluorine in the quenching process.…”

“…Ordinarily, the quenching of gases from which solids condense would be difficult by surface heat exchange or by expansion because of the effects of fouling and erosion. The quench rates calculated by Equation ( 5 ) for the example data are given in Table 4.…”

“…The mixture is subsequently quenched. In the diffusion model (Freeman and Skrivan, 1962), the plasma stream consists of high-temperature and low-temperature regions. The reactants diffuse into the high-temperature region and subsequently decompose to give products instantaneously.…”

A two-layer model has been used to determine the mixing of C3H8 with the plasma stream in the decomposition of C3H, in an atmospheric argon arc plasma jet. The effect of argon flow rates and reactor diameters on the mixing is discussed in terms of @, the mass exchange coefficient between the hot core and low-temperature annular regions in the plasma stream. The model explains well the dependence of conversion on both the specific energy and the axial temperature change of the plasma at an argon flow rate of 8.6 L/min, by assuming that @ ranges from to 'Ilo for reactor diameters of 12 and 25 mm. At a high argon flow rate of 25.8 L/min, @ ranging from ' /*,, to also reproduces the experimental results for the reactor diameter of 25 mm. The range of p suggests that the mixing of C3H8 with plasma stream occurs stepwise.
