2. Physical chemistry of saturated hydrocarbon pyrolysis

2.1 Thermodynamic considerations

From a thermodynamic point of view [1] , the unsaturated hydrocarbons we're looking for are only stable in relation to the saturated hydrocarbons that give rise to them at relatively high temperatures (> 350°C). This fact is illustrated in figure 1 , which shows the variation, as a function of temperature T (in kelvins), of the free energy of formation $Δ G_{form}^{o}$ relative to...
