Abstract
Nowadays, studies on renewable energy sources are increasingly in focus. Hydrogen is considered an attractive option because it allows getting energy of a clean way. One way to produce hydrogen is biomass gasification. However, within this process, there is the formation of tar, which is a severe impediment among the impurities present in the syngas produced. The steam reforming is a widely known technique for the removal of the tar, avoiding equipment damage, and produce H2. In this sense, this paper presents a numerical simulation of hydrogen production from the steam reforming of toluene in a fixed bed membrane reactor. To carry out a dynamical analysis of the behavior of this reactor, the study 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) was solved by Coupled Integral Equation Approach (CIEA). The use of a fixed bed configuration makes it possible to obtain an energetically efficient process, capable of separating the main product with no further supporting process or even expensive units, providing a cost-effective approach to produce hydrogen.
