Abstract
The excessive use of fossil fuels has led to several environmental problems, which directly affect the ecosystem, implying the adoption of stricter legislation. Studies for replacing these fuels with clean and renewable energy sources, without affecting the efficiency and applicability of the processes are needed. Thus, hydrogen has become an interesting alternative since it can be obtained from renewable and non-polluting sources. The association of hydrogen to diesel, used in combustion engines, can reduce pollutant emissions, mainly NOx. One way of achieving such an association between fuels is the incorporation of a steam reforming step of organic fuel, such as ethanol, mixed with recirculated exhaust gases. Thus, this work proposes the simulation of the steam reformer of ethanol over nickel, simulated as a single channel, with recycle current of the exhaust gases of the engine, aiming the production of hydrogen. Ansys Fluent software will be used, the variable proportion of dilution of ethanol in exhaust gases will be evaluated, besides the generation of the hydrogen during the reform. It is expected to observe the effects of the exhaust gases dilution ratio variation similar to the reforms carried out in a higher presence of compounds such as CO and CO2.
