EXPERIMENTAL AND KINETIC STUDY OF SYNGAS PRODUCED BY PYROLYSIS
Краткое описание
This study brings together the one hand the production of biogas (syngas) and
secondly to optimize its quality energetic. The study was carried out while heating a wood species
(oak) in an inert atmosphere (pyrolysis). The pyrolysis at low temperature was chosen to maximize the
amount of biogas while the heating rate was chosen to optimize his quality.
Pyrolysis of oak was carried out in a reactor under a nitrogen atmosphere between room temperature
and 400 ° C, with different heating rates. The rate of rise in temperature affects the quantity and quality
of the pyrolysis products. The main products obtained are three: pyrolysis oil (tar), char (charcoal) and
syngas (non condensable gas).
The chemical composition of the syngas produced is identified by chromatographic analysis. Indeed, in
terms of volume, the syngas produced is consists mainly CO and CO2, its energy is mainly represented
by the CO and CH4.
The evolution of the production of the tars was conducted in part by sampling syngas and secondly by
the thermogravimetric analysis where the weight degradation in the pyrolysis reactor was considered.
The goals of this work are to determine kinetic parameters during pyrolysis decomposition of wood
chips by an isoconversional method. It also relates the kinetic of the main components of syngas,
which are CO, CO2 and CH4.
