Abstract : The applicability of kinetic measurements obtained in induction (ignition) phase measurements such as those made in shock tube and those obtained in the post induction phase by flow reactors has been clearly delineated - particularly with reference to hdyrocarbon oxidation. The usefulness and limitation of global kinetic modelling has also been carefully analyzed. Experimental results show that there appears to be three stages in the paraffin hydrocarbon oxidation process that must be considered if there is to be global modelling. The new element is a well defined initial step most easily recognizable in the temperature range of the flow reactor. This step is the relatively isoenergetic conversion of the paraffin to the olefin. Extensive work with ethane indicates that the conversion rete is proportinoal to the amount of ethane converted. Future work will attempt to explain this functional dependence of this phase of the overall paraffin hydrocarbon oxidation process.
