Biomass as a source of renewable energy has several environmental advantages over fossil fuels. The main advange is the lower net emission of greenhouse gases. Gasification of biomass produces a raw gas mixture composed of hydrogen (H2), carbon monoxide (CO), carbon dioxide (CO2), water (H2O), methane (CH4) and tar. Researches on tar removal usually consider the use of model conpounds such as phenol, naphthalene and toluene. In this study, toluene was used as the tar model compound because it represents a stable aromatic struture apparent in tar formed with high-temperature processes.
The objective of this work has allowed the validation of the chemical species (H2, CO and CO2) by comparing of the optimized values. It was allowed the more complete experiments using simulation to investagte the behavior of Tg and Ts versus the temporal variable. Futhermore, an sensitivity analysis was perform for Tg and Ts using the initial temperature (Tg,0) of the gas phase.
