Ethanol is potentially a promising source for the production of valuable chemicals or advanced biofuels with increased availability. For example, the ethanol has been used as a sustainable replacement for petroleum gasoline, but ethanol has a lower energy density and it absorbed water, which leading to the separation in storage system. As a transportation fuel, higher alcohols such as 1-butanol has much higher properties and that can alleviate many of problems associated with ethanol when gasoline blended with 1-butanol. However, the production rate of butanol yield from fermentation is lower than that of ethanol produce from yeast fermentation process. Thus, ethanol is more available as a basic source for the utilization of valuable chemical products than fuel application. In this study, the catalytic conversion of ethanol to other valuable components investigated over mesoporous silica based catalysts under supercritical condition. |
