Abstract
The biomass can be used as a renewable source with huge potential to cope with environmental concerns derived from the large dependence on fossil fuels and reduce the greenhouse gas emissions. However, within the process of biomass gasification there is the formation of tar, which is a serious impediment among the impurities present in the synthesis produced. The steam reform is a widely known technique for the removal of tar, avoiding equipment damage, and can produce hydrogen fuel that is component is a relevant alternative for reducing environmental impact, which is usually caused by greenhouse gas emissions from fossil fuel use since it is produced sustainably from renewable energy sources. In this sense, this paper presents a numerical analysis of the steam reforming using toluene as model Compound to produce hydrogen in a fixed bed catalytic reactor. In order to carry out a dynamical analysis of the behavior of this reactor, the analysis of a mathematical model was developed to investigate the dynamic evolution of the temperatures and chemical species present in the reactions of reforming. This model is described by a system of Partial Differential Equations (PDEs). In addition, to solve these PDEs, it was used the technique Coupled Integral Equation Approach (CIEA) and with a code in FORTRAN 95 language, that allowed obtaining data about the temperatures profiles and H2 production.
