FUEL 188 |
| Biodiesel and ethanol have shown excellent activity in the catalytic partial oxidation process for the production of hydrogen. The catalyst is stable and able to achieve fuel conversions ~90% and selectivity to form hydrogen ~90%. In this work, we focus on two biofuels, methyl acetate and biobutanol. Methyl acetate is the simplest methyl ester. It is used as a probe molecule to investigate the effect of the methyl ester functional group on the choice of catalyst to prepare better catalysts for biodiesel catalytic partial oxidation. Biobutanol, or 1-butanol, is an alcohol that companies such as Dupont and BP are starting to produce. 1-butanol is a better fuel additive to gasoline than ethanol due to its higher fuel economy and higher mix ratio without the need to modify the engine. We present data on the effects of reactor operating parameters, such as feed ratio and flow rate, on the yield of hydrogen. Atypical results for methyl acetate show that high conversion and high selectivity are not easily achieved as is the case for most other fuels. |
