Abstract
Pyrolysis technology has been demonstrated in recent researches as one of the
most effective and environmentally friendly methods for solid wastes pretreatment
and energy utilization. Pyrolysis is a process wherein organic materials
are exposed to thermal treatment in the absence of an oxidizing agent, resulting
in a solid (char), liquid (tar and bio-oil) and volatile gases (CO, CO2, CH4, and
H2). A two phase (solid-gas) equilibrium model is proposed in this work in order
to simulate the pyrolysis process of wooden biomass (spruce sawdust). The
model is able to predict the amount of solid char, the yields and the chemical
composition of pyrolysis gas for different process temperatures. In this case,
process simulations were done for 600ºC and 800ºC. Aiming the model
validation, an experimental campaign was carried out using batch-scale pyrolysis
reactor. The simulation results have shown a good agreement with the
experimental once.
Keywords: biomass, pyrolysis, modelling.
1 Introduction
The energy conversion of the biomass is considered like a key action to attend
the sustainable developpment objectivs of Kyoto Protocol, because it allows the
reduction of the fossil fuel utilization, since the CO2 evacuated through the
energy conversion process is compensate by the CO2 absorbed through the life
cycle of the vegetals. Biomass, as part of the renewable energy, can achieve zero
emission of CO2 and also can help the sustainable development [1]. Wood and
other forms of biomass represent some of the main renewable solid energy
sources available and provide the only source of liquid, gaseous and solid fuels
[2].
Keywords
