modelling have been summarised in the previous section. The main benefits of the

studies carried out over the past 25 years have been:

1 optimisation of the process parameters to allow the prediction of yields and specification for the production of chemical intermediates.

2 kinetic data has been obtained which aids in the prediction of reaction times and ultimate yields.

3 reaction pathways allow the fast/flash pyrolysis process parameters to be specified for the production of speciality chemicals in significant yields.

4 reactor design and specification is now much simpler due the more data on relevant physical properties becoming available, allowing better design methods.
