Design Aspects of FFR to be Used in Pyrolysis

The literatnre snrveyed above and onr own experience [23-27] identify several important aspects for FFR design to be employed in waste plastic pyrolysis  

Depending on the reactor length, there is a threshold for particle size to begin to inflnence free fall or reaction time and hence prodncts. The reactor length shonld 

All possible means, inclnding provision of mnltiple exit points along the reactor, nse of a carrier gas, and application of vacnnm mnst be considered to facilitate fast removal of gaseous products from the reaction medinm. 

The kind of reaction medinm, i.e. whether it is inert, oxidative, or rednctive, deserves attention because of its substantial effect on the yield and composition of solid, liqnid, and gaseous products. 

Raw material may need some kind of pretreatment. For example, styrene foam can be subjected to heat to make it compact before grinding to fine particles.
