The contribution of homogeneous reactions in catalytic oxidation processes: safety and selectivity aspects

After a brief summary of the main aspects concerning the formation and ignition of flammable mixtures, attention is given mainly to: (i) the identification of risk location in oxidation processes; (ii) how homogeneous phenomena may affect the products distribution in heterogeneously catalyzed gas-phase oxidations; (iii) how the flow regime in the oxidation reactor can affect the flammability limits of the process gas; (iv) the preventive measures for minimizing selectivity degradation and maximizing safety in oxidation processes.
