Influence of the Main Operation Variables

Both the activity and selectivity of the catalysts heavily depend on the following reaction variables  

Henceforth, their respective effect over the catalytic cracking of plastics is described  

Temperature is likely the most important variable affecting the catalytic cracking of plastics. Reaction temperatures are usually in the range 300-450°C. In general, a temperature increase leads towards a parallel activity enhancement of the catalysts. Nevertheless, it must be taken into account that at high temperatures the simultaneous occurrence of thermal cracking reactions is favoured, which may modify the product selectivity.
