Gasoline isooctane oxidation

Some reactions have a very favorable equilibrium constant (K 1), but the rate is very slow. The oxidation of alkanes like isooctane to form CO2 and H2O is an example of this phenomenon. Without a spark to initiate the reaction, isooctane does not react with O2 and gasoline, which contains isooctane, can be safely handled in the air. 

Chen et al. prepared a catalyst for pre-reforming of gasoline [236]. It was composed of 50 wt.% nickel oxide, 18 wt.% lanthana and the balance alumina. The catalyst was tested at a weight hourly space velocity of between 40 and 168 L (hgcai) at 5-bar pressure and 480 °C reaction temperature. The gasoline surrogate was composed of 74 wt.% isooctane, 20 wt.% xylene, 5 wt.% cyclo-hexane and 1 wt.% 1-octene (average... 

O Connor et al. investigated the partial oxidation of gasoline and gasoline components, such as cyclohexane, n-hexane and isooctane over washceramic monoliths carrying 5 wt.% rhodium supported by y-alumina [248]. The stoichiometric O/C ratio of 1.0 revealed the best results with respect to activity and selectivity.
