Fischer−Tropsch (F-T) synthesis is a well-known route to convert synthesis gas (H<sub>2</sub> + CO) to higher hydrocarbons. Biomass based F-T fuels is a viable option for transportation since it can be blended with conventional fossil fuels to abate environmental pollution. We have previously studied F-T synthesis in Si-microreactor using silica sol-gel coated-metal catalysts. In order to increase the surface area of the catalysts, we have considered mesoporous silica such as SBA-15 as support in this study. The catalysts were characterized by TGA-DSC, SEM, EDX, BET and XRD techniques. The catalysts were ball milled with PVA (polyvinyl alcohol) into stable slurries to coat the channels of the Si-microreactor. Syngas conversion using Cu-Co/SBA-15 and Cu-Fe/SBA-15 catalysts were investigated at 1atm. While Fe/SBA-15 yielded ~95% ethane and 5% methane at 350°C, 12%Ru12%Cu-MCM-41 showed ~100% ethane selectivity at 250°C. Results from our ongoing experiments and computational studies of bimetallic catalysts will be presented.<br/>
