Carbon-molecular oxygen reaction spaces

Combustion is an oxidation-reduction reaction between a nonmetallic material and molecular oxygen. Combustion reactions are characteristically exothermic (energy releasing). A violent combustion reaction is the formation of water from hydrogen and oxygen. As discussed in Section 9.5, the energy from this reaction is used to power rockets into space. More common examples of combustion include the burning of wood and fossil fuels. The combustion of these and other carbon-based chemicals forms carbon dioxide and water. Consider, for example, the combustion of methane, the major component of natural gas ... 

A similar type of mechanism was also proposed for carbon tetrachloride oxidation, important steps in both mechanisms were the adsorption of the chlorinated hydrocarbon on the Br-nsted acid sites and dissociative adsorption of molecular oxygen on Co cation sites. The formation of CO and CO2 products were via parallel reaction pathways, with little or no CO2 formed by sequential CO oxidation. The formation of phosgene as a reaction intermediate has been identified during CCL, oxidation at space velocities above 15,000 h 4n a wet feed stream and as low as 2,400 h Mn a dry stream. The selectivity of phosgene also increased with time on line as the catalysts deactivated from 99% conversion to ca. 10% conversion after 22.5 h use.
