The analysis on the feedstock pyrolysis characteristic and the impacts of process parameters on pyrolysis outcomes can assist in the designing

operating and optimizing pyrolysis processes.This work aims to utilize both experimental and modelling approaches to perform the analysis on three biomass feedstocks—wood sawdust

bamboo shred and

Jatropha Curcas

seed cake residue

and to provide insights for the design and operation of pyrolysis processes.For the experimental part

the study investigated the effect of heating rate

final pyrolysis temperature and sample size on pyrolysis using common thermal analysis techniques.For the modelling part

a transient mathematical model that integrates the feedstock characteristic from the experimental study was used to simulate the pyrolysis progress of selected biomass feedstock particles for reactor scenarios.The model composes of several sub-models that describe pyrolysis kinetic and heat flow

particle heat transfer

particle shrinking and reactor operation.With better understanding of the effects of process conditions and feedstock characteristics on pyrolysis through both experimental and modelling studies

this work discusses on the considerations of and interrelation between feedstock size

s energy usage

processing time and product quality for the design and operation of pyrolysis processes.
