Throughout this study, the major goal is to analyze the product distribution of methanol combustion at different reaction conditions, such as, varying space velocities, different initial temperatures, on 2% Pt/Al2O3 catalyst. The catalyst support material, alumina, was prepared by using a single-step sol-gel method and platinum was added by using the impregnation method. The reaction was conducted in a tubular reactor. In this work, the maximum steady state temperature at room temperature experiment was achieved almost same within the error for 2.4 s-1 and 2.8 s-1 space velocity for fresh catalyst, and also, the conversion to CO2 during the methanol combustion reaction for all the space velocities (2.4 s-1, 2.8 s-1 and 3.1 s-1) were found to be ~100%. Another parameter that was studied was the temperatures below the room temperature. The reaction was performed at -13oC, 0oC, 7oC and 15oC temperatures. With decreasing initial temperature, the steady state temperature was also found to be decrease. This was correlated with the product distribution and with decreasing initial temperature, CO2 conversion decrement was observed.. Methyl formate was detected to be the main byproduct that was produced under all the space velocities at temperatures lower than room temperatures. The catalyst was active even at -13oC. Therefore, it showed that it could be used as a catalyst for an external heater to provide necessary heat to reach the direct methanol fuel cells operating temperature at and below room temperature. Other than the other catalysts that was investigated in literature, our catalyst does not need to heat up the reactor. Once the fuel is supplied, the system reaches the necessary operating temperature by itself. This is desirable especially in portable DMFCs. The catalytic methanol combustion system investigated in this study seems to be promising to easily replace the lithium-ion batteries for portable electronic systems, especially ones used in the military.
